GC Engine Oil Question

[cdaigle430]

So dudes, you convinced me to switch over to 5w40 for this oil change coming up. So educate this here dummy, what's the downside to 5w40 rotella in summertime, none right? And any issue mixing it with 15w40 I have left over, come next oil change in spring/summer?

Also right quick, are you all changing your coolant every year regardless of hrs put on it? I put in the hd extended life stuff last fall.

I have not changed it yet and its 11 years old-i dont think im very smart. I Will change it next spring...

I had to come back here, as this thread kind of haunted me. I was noticing that as it got colder, the 15W-40 I had put into Cliffy was indeed making the engine a little harder to start. As I do not yet have AC power to the tractor shed (next year..) I kept thinking about the reply about using Rotella T6 0W-40 as it is easier to start with in colder weather. Finally, I went out and got a jug and changed it out. Engine has been starting quicker since.
