What was the oil pressure before you changed it /and what is it now/and what type and grade of oil did you put in when you serviced it. As for burning oil which is the smoke problem is it only on start up/all the time driving/only after idleing. As its main problem is the oil must be thinner oil than what was in there,as 20W 40 Shell and a new filter should have brought it back to normal/Plus have you got any oil leaks on the engine /and how many miles on the clock. Let me know how you go ASAP. Ron Nov 04, 2009.
