it had 5w40 synthetic oil in the engine when i bought it, but i put in 5w30 part synthetic as a top up i didnt change the oil fully. after the top up i started hearing a tapping on a cold start after the car warms up the tapping dissapears or is vey faint. im doing a full oil change tomorrow! u say put oil in the filter before it fitted how much? should i also use a engine flush before i drop the oil out or the car or not bother.. thanks for the help
hi can i ask u a question lol,,hi i put semi synthetic oil in my subaru impreza wrx 2003 after buying it. the oil was quite low but still enuff on the dip stick. i notice on the service sheets the car always had 5w 40 synthetic used always. since putting the oil in i seem to be suffering from a knocking/tapping noise at low revs when cold. i think it must be piston slap as it dies down when the engine is warm. but seems strange how its started since ive put the new oil in. is it the thinner oil or part synth that has caused it? what can or should i do to stop it.
