Hello all ,
I've been getting very poor MPG from my 1989 230TE , and after asking around someone suggested that the engine could be all choked up as I do a lot of stop/start short journeys . So off I went for a foot to the floor blast , and low and behold at above 5,000 RPM there was quite a bit of whiteish smoke , bearing in mind that I was going about 85 MPH so for me to see it , there must have been plenty of it . So am I doing the right thing ? or completely the wrong thing ? . If indeed the engine does need a de-coke approx. how much £££ am I looking at ? , or could it be a valve / valve seat problem ? or am I expecting too much for an engine with 134,000 on the clock ? . Finally my oil pressure gauge always reads 3 untill the engine is fully warmed up , and after a long run , when the engine comes back to idle it goes back to 1.5 to 2 , but it always goes back upto 3 again once the engine is under load , is this normal ? .
Thanks
