Ease of ordering, best value for money.

Ease of ordering, also I’m a regular buyer of their products. Mainly CRD (CRD is for Diesel only) and FTC Decarbonizer which is a fantastic product in diesel and petrol vehicles. Latest purchase is clean power due to me getting a petrol vehicle. Ordered Friday and literally delivered following Monday morning as I’m typing this review. Can’t fault customer service, any questions just give them a call or send an email.

Its Good Sheeit!

Easy to use, good value, does exactly what it says on the bottle.
After using the Engine flush on my just bought 3.2 diesel Pajero, the oil came out like black as f, horsepiss! The new oil looks clean as new after 4 weeks. I’m using the Ftc carboniser and the CRD additive in the fuel, and the turbo is whistling happily! Engine feels stronger and smoother and fuel consumption is better, definitely! Its Good Sheeit!!

DTC Decarboniser Product

Your company is always quick to act on orders and delivery of product. Also find Decarboniser product good with DPF filter so far.
Any recommendations for a Diesel fuel additive also if Australia goes to a lower grade fuel? I have concerns with using it. What are your companies thoughts? I have a 2018, 2500 Ram.

Limited Shef Life

I purchased FTC in a promotion pack 2 years ago. The second bottle now has a sediment on the bottom of it. When shaken it does not dissolve back into the liquid. I'm concerned that this will now foul the fuel filter and/or the pump. Nowhere in their literature is there any mention of shelf life. It's a very expensive product that apparently works well, but with the prospect of throwing out nearly a whole bottle make it extremely expensive. I travel only about 5 to 6k kilometers each year so I don't know if this product is for me.

In my Kia K2900 truck with 350,000

In my Kia K2900 truck with 350,000, after one tank, I noticed improvement in acceleration response. After 2 tanks, it's like I have a new motor. Very peppy. I also used the decarbonizer on the Mrs Pajero with 330K but didn't tell her. 2 tanks in and I asked her how her car was running. She said "did you do something? Because it seems much smoother when I accelerate.". Good on you Cost Effective Maintenance. I've been telling everyone at work and have just started on the work fleet.
