Archoil AR9100 Advanced Friction Modifier Oil - 200ml

Engine Protection

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.Read full review

Archoil

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.Read full review

Quieter Diesel Now!

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

Yeah - Archoil AR9100 friction modifier makes a difference

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 itRead full review

Engines' Elixir of Life.

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.

outstanding performance

as a vehicle technician, i had a high level of expectation for this product, having used p.t.f.e. products in the past i knew what to expect, but, what i got , well it far exceeded my expectations. I put some in my manual transmission and literally overnight after only one journey the difference was dramatic, all of my gears were much smoother and less notch y, so i put some in my engine and again, much smoother running, it did seem a bit pricey, but i guess you get what you pay for.Read full review

Great stuff, you will notice the difference on even a young engine!

Just treated my 67 plate transit custom sport to a full service with just over 8K on the clock. Put the Archoil in at the recommended ratio, and within a few miles the difference was very noticeable. The engine was alot smoother at idle speed and under acceleration. Will definitely buy some more for my next service.Read full review

Quality

I have used this on a engine with noise valve adjusters withing 100 miles the noise had gone and the adjusters worked better. I use it every oil change now not seen anything that works as well.
