Been using these products for a few years now absolutely the best never had any issues.
With fuel shortages not knowing what’s coming from the bowsers these products are the best insurance you can get to keep fuel contamination out.
Had the items in 3 days excellent service.

Great product for old diesels
I’ve had great results with the FTC Engine Decarbonizer and CRD fuel enhancer in my 2011 Pajero over the past couple of years. It’s got 300k on the clock and these products made a huge difference to performance, idling and smoke. My only criticism (and I’ve seen this in other reviews) is that the Ezypor cap leaks in hot weather and makes a huge mess in the boot and stains skin, paint, etc. Would be great to see a fix for this from them. Otherwise, highly recommended.

Look no further for technical information
My experience was that it was easy to buy online especially given the amount of detailed information available. Despatch and delivery were prompt. I can't comment on the effectiveness of the product yet - in fact It's probably one of those things you may never know but these people certainly have a lot of information on injectors, fuels, etc etc.

Reliability Rules
Ordered online, turned up within time stated.
I have been using Cost Effective products for a while now as a preventative maintenance tool for reliability.
Everything I've used the products in run smoother with no issues of unreliability. I do recommend these products.

Sensational product - worth the money
Great product - makes the 200 Series Landcruiser run so nice, and reduces injector/ pump noise.
DPF runs cooler and cleaner.
Sensational customer service, quick delivery times as well.

FTC Decarbonizer.
Have started using the product and in one tank of diesel have really noticed the difference. The ute starts better and runs well especially noticed on the country run.

CRD Fuel Enhancer.
The Company was recommended by a friend. I wasn’t sure what product would be best for my 2022 Diesel hilux so i phoned them. They were very helpful and didn’t try to oversell.
I purchased CRD Fuel Enhancer, and Cleanpower for my petrol Silvia. I made the order and it arrived within 3 days. Excellent service from start to finish. Just trying the products now but will definitely buy again.
