CASE STUDY BERTRAND & FRERE

CONSTRUCTION – REDUCING ENGINE FAILURES IN QUARRY & HEAVY EQUIPMENT

CUSTOMER BACKGROUND

Bertrand & Frere Construction , based in Ontario, operates across quarry crushing, gravel transport, excavation, and floating. Their fleet includes heavy-duty equipment such as wheel loaders, tractors, stationary engines, dump trucks, mixer trucks, and excavators — all working in high-contamination environments.

THE CHALLENGE

Harsh conditions led to oil contamination and accelerated engine wear . Frequent full oil changes were needed: o Wheel loaders: manufacturer oil and o Tractor units: oil and filter changes filter changes every 500 hours. at 100,000 km or annually. Costly repairs, including sleeve pitting on Cummins engines , required tear-down inspections of cranks and bearings. The company needed a way to extend oil life, reduce contamination, and prevent costly component failures.

KLEENOIL’S SOLUTION

Bertrand & Frere first trialled two Kleenoil Bypass Filters on:

A 966D Caterpillar wheel loader . A Western Star 350 Cummins big cam engine . Maintenance Approach with Kleenoil Wheel loader: Kleenoil filter changed every 200 hours ; manufacturer filter + oil change every 500 hours . Tractor: Kleenoil filter changed every 20,000 km ; manufacturer filter + oil change at 100,000 km .

Independent oil samples were sent to Wear Check and Crothers for analysis, confirming significant improvements in oil cleanliness and stability

EVIDENCE OF PERFORMANCE

Cleaner Oil: Independent labs verified oil quality improvements. Extended Intervals: Oil and filter life extended safely under heavy-duty use.

Engine Protection: Sleeve pitting issues on Cummins engines reduced. Tear-down inspections revealed bearings and crankshafts in excellent condition compared to pre-Kleenoil history. Fleet Expansion: Success led to the purchase of 30 more Kleenoil units, installed across loaders, shovels, Euclids, dump trucks, and mixers. Contamination Control: Filters captured fuel, water, antifreeze, aluminum, and copper sediments — removing threats before failures could occur.

BENEFITS TO BERTRAND & FRERE

Reduced Engine Failures: Early warning and removal of damaging contaminants. Extended Oil Life: Longer drain intervals reduced oil consumption and labour. Lower Costs: Reduced repair costs from avoided sleeve pitting and bearing failures. Fleet-Wide Confidence: Expanded to 30+ units across all heavy-duty machines. Independent Verification: Oil labs confirmed “very satisfactory” results.

CLIENT TESTIMONIAL

“Sleeve pitting on a Cummins engine was why we opened an engine and inspected the crankshaft. The bearings were done at the same time, and let me tell you, we were very well pleased with this product. Fuel, water, antifreeze, and metal sediments were trapped by the Kleenoil filter before failure. I strongly recommend Kleenoil to anyone.”

CASE STUDY HYDRO ONE – ELIMINATING WATER CONTAMINATION & EXTENDING HYDRAULIC OIL LIFE

CUSTOMER BACKGROUND

Hydro One operates a large fleet of hydraulic and hydrostatic trucks across Ontario, supporting powerline and electrical utility work. The fleet requires semi-annual dielectric testing to ensure safety when working near live electrical lines.

THE CHALLENGE

Water contamination in hydraulic oil posed a serious risk. If water remained in the system and a hose blew, electricity could transfer from the power lines to the truck. Trucks that failed dielectric tests had to be taken out of service, flushed, and refilled with new oil. This process was time-consuming, costly, and disrupted operations .

KLEENOIL’S SOLUTION

Hydro One installed Kleenoil bypass filtration units across the fleet beginning in 2004.

Key Features Kleenoil cartridges remove 99.95% of water and particles down to 1 micron. Filters fitted to all hydraulic and hydrostatic units (~1,500–1,800 units). Cartridges replaced every 300 hours or at 6-month inspections . Oil samples taken regularly to monitor condition.

CASE STUDY EAST YORKSHIRE MOTOR SERVICES – EXTENDING OIL LIFE IN BUS ENGINES

CUSTOMER BACKGROUND

East Yorkshire Motor Services (EYMS) is a long-established bus and coach operator, running since 1926 with over 800 employees. Their fleet includes Volvo B7 and B9 buses , which faced recurring sooting problems that led to high oil contamination and increased maintenance demands.

THE CHALLENGE

Volvo B7 engines were known for excessive soot generation. Frequent oil and filter changes increased costs and downtime. EYMS needed a way to reduce oil-related maintenance while keeping buses on the road, ensuring reliability for daily passenger operations.

KLEENOIL’S SOLUTION

In 2010 , EYMS began trials with Kleenoil filtration and independent oil analysis by Millers Oils . Based on early success, the system was fully installed across the fleet in 2012 , first on the B7s and later extended to the B9s.

The maintenance approach was adapted as follows: Kleenoil cartridge changes every 10,000 km. Oil & standard filter changes at 60,000 km. Regular oil sampling during each service interval.

In many cases, the original spinner filters were removed, saving an additional £40 per bus per month .

RESULTS ACHIEVED

Oil Analysis & Cleanliness

Independent oil testing confirmed oil quality remained in good condition after 7 months without an oil change (see analysis reports on page 4). Water contamination remained zero . Soot and particulates were dramatically reduced, with only a minor increase that was considered normal for operating conditions. Cost & Labour Savings By using Kleenoil cartridges instead of full oil changes, EYMS saved on: o 5 out of 6 oil and filter changes . o Significant labour time and downtime (cartridge swaps take 15 minutes vs. full service). Across a fleet, even small per-vehicle savings compounded into substantial cost reductions. Reliability & Longevity Cleaner oil reduced engine wear and breakdowns. Longer oil life meant less unscheduled maintenance , improving fleet availability.

WORK CARRIED OUT

Unit operated continuously for 14 days (including weekends even when the baler wasn’t running). Two filter changes performed during the hire period. Oil samples were taken before, during, and after treatment for independent verification.

RESULTS ACHIEVED

Particle Count Reduction (per 100 ml):

14 micron: ↓ 99.5% 6 micron: ↓ 98.2% 4 micron: ↓ 84.5% Significant removal of the most damaging particles (14 and 6 micron). Chromium contamination was effectively removed. Longer operation would continue to reduce 4 micron counts. Oil replacement avoided. Investment: just the affordable hire cost . Net saving:— payback achieved instantly. Operational Impact: Machine continued running during filtration with no downtime . Oil restored to safe cleanliness levels for continued use. Financial Impact:

BENEFITS TO EYMS

Reduced Engine Wear: Extended life of Volvo B7 engines with known soot issues. Improved Oil Hygiene: Oil maintained “as new,” cutting abrasive contamination.

CASE STUDY EXTENDING ENGINE LIFE & REDUCING COSTS IN DRILLING SUPPORT OPERATIONS

CUSTOMER BACKGROUND

A leading drilling support company operating a fleet of PACCAR 10 diesel engines in their coiling division faced high operational costs and downtime risks. According to the manufacturer’s guidelines, each engine required: Oil & filter changes every 250 hours A complete engine overhaul at 12,000 hours With dozens of engines in continuous operation, this meant significant maintenance expenditure, lost productivity during service, and the logistical burden of frequent oil changes.

THE CHALLENGE

The company wanted to:

Reduce high oil and maintenance costs . Extend engine service intervals without compromising reliability. Avoid expensive early engine overhauls.

KLEENOIL’S PROPOSAL

Maintain consistently high oil quality. Extend the useful life of the oil. Kleenoil recommended installing a Heavy Duty Bypass Filtration System designed to:

Reduce wear on engine components. Verify performance through oil analysis at set intervals.

IMPLEMENTATION

The Kleenoil Heavy Duty Unit was easily installed, with oil supplied from the pressure switch and returned to the sump (see installation photo, page 1). The engine continued on its regular 250-hour service schedule, but oil samples were analysed before any interventions. At the 12,000-hour mark, where a full overhaul was normally required, oil analysis showed excellent quality and minimal wear — meaning the overhaul could be safely postponed.

RESULTS ACHIEVED

Extended Oil Life: Oil and filters were not changed at the first 250 hours. Service continued smoothly until 2,000 hours before requiring a change. 8x Oil Life Increase: Oil life was extended from 250 hours to 2,000 hours, delivering a saving of $13,411.52 per engine. Deferred Overhaul: The standard 12,000hour overhaul was avoided, saving $20,000 per engine in downtime and component costs. Extended Overhaul Interval: The engine overhaul was eventually carried out at 24,000 hours. When inspected, components were classed as “as new,” meaning wear was negligible. This delivered an additional $20,000 saving. Hard Savings: Total direct savings reached $53,411.52 per engine. Soft Savings: Additional benefits included improved cash flow, reduced inventory requirements, and smoother engine performance.

CUSTOMER OUTCOME

The financial and operational impact was so strong that the customer immediately installed Kleenoil filtration systems across their entire fleet of engines.

KEY TAKEAWAYS

Oil changes reduced from 96 to just 12 over 24,000 hours. Minimal engine wear, validated by independent measurements. Over $53,000 hard savings per engine, plus significant operational improvements. Proven return on investment, leading to fleet-wide adoption.

CLIENT TESTIMONIAL

“We extended oil life eightfold and doubled the interval before overhaul without any compromise in performance. The Kleenoil system paid for itself many times over.” MAINTENANCE MANAGER, DRILLING SUPPORT COMPANY

CASE STUDY NOTTINGHAM RECYCLING LTD – EXTENDING OIL LIFE & REDUCING MAINTENANCE COSTS

CUSTOMER BACKGROUND

Nottingham Recycling Ltd (NRL) is a waste management and recycling company working toward a zero landfill policy. As part of their green initiative, they sought ways to reduce oil waste, minimise maintenance downtime, and improve equipment life while cutting operational costs. They purchased a refurbished Cummins Gen 1250 genset through I.P.G and chose to install Kleenoil filtration alongside a programme of monthly oil condition monitoring.

THE CHALLENGE

Traditionally, standard practice required: Regular oil and filter changes.

High labour input and downtime. Significant costs for oil disposal. NRL wanted to see how far they could extend oil life without risk, while maintaining reliability and aligning with sustainability goals.

KLEENOIL’S SOLUTION

On 12/05/2011 , three Kleenoil SDU9788KU85 units were installed (one per 50-litre sump capacity) on the Cummins 1250 genset. Kleenoil cartridges were replaced on Parker’s own maintenance schedule, allowing fewer full service visits. Oil condition monitoring was carried out to ensure continued reliability. Units installed across a wide range of hire equipment provided standardised maintenance benefits fleet-wide.

IMPLEMENTATION & MONITORING

Over the course of 12 months , oil condition was tracked carefully:

Early Operation (4–750 hrs): Rapid drop in contamination, zero water content, and negligible wear metals. Mid-Term (1124–1655 hrs): Consistently low contamination, excellent chemistry, no water ingress.

At 2885 hrs , oil and filters were finally changed — meaning NRL had successfully eliminated 11 out of 12 scheduled oil changes during this period. Extended Operation (2078–2885 hrs): Oil remained clean with wear metals at negligible or reduced levels.

RESULTS

Quantitative Benefits

Oil Savings: Avoided 11 x 177-litre sump oil replacements. Filter Savings: Avoided 5 Cummins filter sets. Labour Savings: Considerable downtime eliminated. Recommendation: Based on results, Kleenoil advises a 500-hour cartridge change and a 1,500 hour oil & filter change , saving 2 out of every 3 changes. Condition Improvements Water Removed: All traces of water were eliminated across every analysis (see graph on page 8, showing water at zero throughout). Contamination Controlled: Sharp reduction after installation, then maintained at a consistently low level. Wear Reduced: Metals stayed negligible, proving reduced engine wear.

COST ANALYSIS

The quick-glance costing chart clearly shows Kleenoil dramatically reducing oil, filter, and labour expenses compared with traditional maintenance. By substituting monthly cartridge changes for full oil/filter replacements, NRL not only cut direct costs but also avoided labour intensive downtime.
