When to switch to synthetic on g62
I have a g62 with about 3-1/2 gallons through it with lawnboy oil and am interested in trying synthetics. I know there has been thread after thread on the pros and cons of synthetics vs. non-synthetics, but most info that I have read just say "switch over after it is broken-in". Is 3-1/2 gallons enough break-in to make the switch?
Thanks,
