synthetic vs non-synthetic
Well I was planning to change the oil in my 636 when I stopped and wondered. I thought the guy I got it from said it had synthetic in it, but I cant remember. Is there a way to tell if there is or not?
i always used synth until i started reading up on the use of the diesel oil....
but either way as stated above your golden with whatever you use
