I used this stuff last week . Nearly at the end of the tank diesel this week after a few long drives on the weekends and short week day commute journeys. I have noticed the fans have not come on when parked up after short journeys as it did when i first had the car but that could be because it had been sitting on the sales forecourt for a bit and not been driven .
Had my adventure 110 CFHA about 3 months now. Great car for country roads and motorways . nice and comfortable . I do find that in normal city driving it really doesn't like being in 4th gear unless I am doing at least 40.
the new speed limits in wales of 20 mph on some roads I find myself in third gear most of the time . my car is on 98,000 miles so i suspect its not as smooth as brand new turbo or car. But then again i am used to petrol cars and tuned ones at that
