Here’s a few problems that destroy engines




WHITE SMOKE at Cold Start. Glazed bores, sticking rings or crook injector! Use FTC DecarbonizerFlushing Oil Concentrate and Cleanpower (or CRD Fuel Enhancer) respectively.

Sludgy diesel engine oil regularly causes power loss, oil use, poor oil pressure, smoke and overheating under load. Evan Yates used Flushing Oil Concentrate, with a fresh charge of clean oil, to thoroughly clean out his Toyota Landcruiser Troopy. An extra 2L of goo came out when he drained the sump. As Evan shows in the photo he sent us, the Flush pulled a lot of sludge into the clean oil.


It's abrasive and shortens engine life, causes piston ring fouling, loss of performance, and can really get out of hand. Daniel Taylor (WA) owns one of the ever popular Nissan Patrol TD42 GU’s and his is immaculate, well maintained and looked after. Dan reported a bit more power after the Flushing Oil Concentrate was used, but was totally blown away by how clean his oil remained. Even 2000km on the fresh oil and you can see how clean the oil is on the dipstick from the photo he sent through to us.



Crankcase blowby and/or oil use are worrying signs for truckies, because it typically means that an expensive engine rebuild will be recommended by their mechanic or equipment supplier. The cost these days generally starts at $20,000 and can go up to $60,000.

When you're faced with a possible rebuild, you need to ensure that your money is well spent! Our findings over 30 years have shown us that roughly 80% of trucks with blowby still have wear within acceptable levels, but the real problem is they are heavily fouled with carbon and sludge. This is the most common cause of piston ring sticking, blowby and oil use. Clearly, if you’ve got blowby or oil use, your first step should be to restore the engine to clean condition. It’s dead easy, low cost, and there’s no downtime. Simply use our Flushing Oil Concentrate with FTC Decarbonizer, and in 80% of cases, your engine will reduce blowby and oil use. The majority of our customers, who are able to monitor their fuel use, report that they are saving much more diesel than it costs to use these products.

Reduce truck blowby


Like all race cars that work to the limit, they’re under amazing amounts of stress. Ron Lange (from MotorCare 4WD) is a fastidious mechanic who specializes in Mitsubishis. This is the drift car he built. Ron was keen to reduce operating temperature through his engine and drivetrain, as this would mean less wear and internal stresses. AW10 Antiwear proved itself, and he also attributes it to cutting 1 second from his lap time. Ron now delights his customers by using Cost Effective Maintenance products during vehicle servicing. 


Engine carbon accelerates wear, saps performance and economy, and can also cause turbo failures, EGR problems and much more. Sometimes, it’s just from too much city work. Bob sent this photo in of his old Discovery. You can see from the outside of this engine that she’s an old girl, and done a lot of work. Inside, however, was a surprise for the mechanic who lifted the head. Clean as! Bob's been using FTC Decarbonizer. No hard carbon at all & good as gold! Lots more life in the old Disco yet! 

It's now a major killer of engines. Once mechanics see bad sludge build up, they invariably tell their customers to sell it or rebuild the engine. The sludge can really bake on, and when it does, it is almost impossible to remove. It's very tough, but it is possible to remove by following our special instructions for petrol engines using Flushing Oil Concentrate. This flush was performed by Motorcare 4WD.


Vehicle of machinery woes?

Bring YOUR problems to Cost Effective Maintenance...

At Cost Effective Maintenance, with over 30 years in business, our goal is always to provide YOU (our customer) with the most cost effective solutions to YOUR maintenance problems. Our range of products can be used in 2 ways...

  1. Corrective Maintenance. Properly solving an existing problem with an engine, transmission or other component at low cost, easily and with no or minimum downtime. Does YOUR vehicle identify with anything on our Problem Solver Checklist? (Have a quick look below to see if there's anything you need to do.)

    It doesn’t matter if you have…

    …we’ve fixed plenty of them already! But just as important, we prevent these problems recurring!

  2. Advanced Preventative Maintenance. This takes the normal recommended maintenance and log book type service regime to the next level, where the use of superior industrial grade fuel and oil chemicals produce operating benefits, performance and efficiency improvements. A major benefit, particularly for farming and commercial fleet operators, is the substantial increase in engine, transmission and other component life. Advanced Preventative Maintenance is very popular with our trade customers, who build a loyal following by achieving a superior result for their customers.

How to keep your old machinery working for longer, with better reliability, and keeping your new vehicles always performing like new relies on these 2 principles.


Some of our successes include...

1. Pioneered the fix for diesel engine oil going black as soon as it’s changed

2. Provided a safe means of deglazing diesel or petrol engines

3. Lowered horrific levels of diesel smoke from PNG’s high altitude Porgera gold mine

4. Pioneered procedures that have saved literally thousands of engines from mechanic recommended rebuilds

5. Eliminated valve failures in Cummins 1710 & Caterpillar D348 engines at BHP & Rio Tinto mines

6. Pioneered a low cost fix for common rail diesel engine problems

7. Operators of Caterpillar D11R dozers were getting 8000-10,000hrs engine life, with many failures as early as 3000-4000hrs. This was against a Caterpillar recommended 12,000hr overhaul. Caterpillar couldn’t come up with a fix, yet CEM brought a fleet of 10 x D11R’s at a BHP mine to 18,000hrs service life…a clear 50% above Caterpillar target!

8. Keeping older vehicles and machinery in commercially productive service for much longer

9. Reducing operating temperatures, stress and wear rates in gearboxes (both manual and automatic), diffs, final drives, hydraulics

10. Increased coal production efficiency by 5.1% at a Rio Tinto mine.

Roothy gives AW10 Antiwear the thumbs up...

"This stuff is the greatest. It has to be the slipperiest thing this side of a banana peel on a boat ramp. Bugger me! Old Milo (Landcruiser Troop carrier) is shifting gears a lot sweeter since that injection of AW10. I felt the slicker change almost immediately. But the ultimate test was chucking a cap full of oil additive in the two-stroke fuel in Mungo's ancient 25HP Mercury outboard. The bloody thing ran smoother and rattled less almost straight away." This is what well loved and respected bush mechanic, "Roothy", who writes for popular Australia magazines 4WD Action, Caravan and Motorhome, and Live to Ride, had to say about Cost Effective's engine oil additive AW10 Antiwear.
