Lucas Oil 40016 Complete Engine Treatment-473ml

This stuff actually works. Put it in oil and fuel of 2006 freelander with 105000 m and feels smoother and drives better. Works better than mixing two stroke in with diezel.

The cleaner was brilliant. Can see why it is number 1 in USA. so good on 3monthly order now. Fuel flow is good and has improved performance while using less fuel.

Purchased on the advice of my mechanic, for an old diesel with 185k miles on it, that was having problems passing the MOT emissions test, which had had the normal off the shelf fuel treatments put through it but remained substantially over the limit. Put this stuff in the tank and ran for 100 miles before a retest. Tester was shocked it got through on the fast pass on the retest after being so high before.

Seems an ok product.

Does the trick

I did not notice any benefits of using this sadly

Used this on my subaru forester diesel 130,000 miles, it had a flat spot at 2500 rpm and top end rattle. The flat spot has gone and runs smoother so less rattle. Too early to see if milage has improved, still got a 1/4 of treated fuel to go.

This stuff is unreal, makes my van run very smooth when added to fuel
