Remeber that swapping oil every oil change is bad for your motor. Every oil will leave deposits in the motor. Some oils will clean out the other oil's deposists, which will lead to little tiny chunks of stuff floating around. The best thing to do is stick with whatever band oil you are using. Russ
Not to disagree with you, but on a well-maintained motor, the buildup should never reach the point where cleaning it out will cause any problems. Now, if the engine has been neglected, even a little, it can be a whole different story. My WRX has 48k on it, and I have changed the oil 21 times. I'm not too worried about buildup
oh to be a mechanic that loves a wrx.... I am still doing the mobil that the dealership has been putting in since day one, but have heard of a few people that have switched to synthetic, something ive been pondering but shall do some searches here over.
we just ahd a customer change their oil... well lets say we did it like 5 times to flush it... it literally looked like the car was taking a dump..... it was like a poop log coming out of the drain plug... I think that is the build up Russ ios talking about.. ha h ha needless to say his car is still in our parking lot as it keeps overheating as his radiator looked like his oil.. like someone had pooped in it... REGULAR OIL CHANGES = SMART IDEA
