Just mixed this with new engine oil, time will tell if its any good or not so cant comment on it yet. 8/02/2019 After only 800 miles it has made a difference to my 4.6ltr v8. Had a few tappets that made a noise, mostly exhaust, this has vertualy made them all faily quiet. Also it has made my modified engine a lot smoother, not sure if it's improved mpg as it is thirsty any way. Oil is changed every year, AR9100 is added every time regardless of mileage and it never higher than 1000 miles. This is a special supercharged engine and mainly for showes with the occasional Sunday run. Getting dear, may look at other types with a better price.

Archoil is the best product I've ever come across I was introduced to this product by my yunger brother who had problem starting his Audi A3, with using Archoil friction modifier and petrol additive from arch oil it made a good difference to my honda jazz which is in perfect running condition but I still give this product a try and would recommend to anyone who would like their car or any vehicle running in perfect condition should try arch oil, if you have used Preston coolant then you will love to no haw good arch oil is. Archoil also does grease which is really the best on the market.

I had just bought a Kia Sportage 2.0 CRDi awd with 132,000 on the clock and whilst it was quieter than a Qashqai I once owned I was looking for a oil additive to give it a little 'help' I usually figure you get what you pay for so after searching and review various products (and ignoring the jargon) I figured I'd go for this one, its not cheap, over £20 for a small 200ml bottle. So it arrived in a company printed box and was well packed,a good sign.. I added this to a warm engine (it had just been serviced), started it up and expected..nothing as it turned out, lol, I know,it needs time to 'get round'. But after a weeks general driving I would say the engine is now perceptibly quieter and smoother, to me anyway. (I wish I had done a decibel test now) I cant really say if starting is easier or not, maybe in winter it makes a difference. Also I had not owned the car long enough to compare MPG before and after as it were. I would say it is a good product with noticable results and if it does save on MPG then its worth putting in at every oil change. If you want your diesel a bit quieter, get some..Read full review

It took maybe a few days for the effects of this little liquid gold (250ml) to be realised once it was added with fresh oil and filter and the car drives better. My excellent mechanic recommended the old engine oil is flushed out, not just drained, which makes sense because if not, the AR9100 will clean it and it remains in the fresh oil, which is counter productive, so it's more efficient this way. All of a sudden the car was smoother and gear changes were even better on my A5 3.0 TDI Quattro Sport. My Tiptronic box was good and it just got a whole lot better. I started using Archoil 6850 Diesel treatment simultaneously. This stuff is also worth getting. I will use this on any car in the future, it's well worth it

I've used friction reducing additives in my petrol and diesel vehicles for years and they really help to prolong the life of engines. Engines run quieter, more smoothly, in addition to being cooler, and start from cold quickly. For anyone wanting to keep their vehicle for a long time then this slick substance is essential.
