I use GC in my snowblower, but wasnt sure I wanted a 0W during startup for my tractor (which is only used in warm/hot weather)
I was able to find a couple quarts of various synth I had (Pennzoil Plat and QSUD), Ill be changing the oil again at the end of the season anyway....will be on the lookout for some decent deals on a decent synth, maybe something like Napa full synth.
