Is rotella T5 good to use in this generator?
Thanks

Well, any motor oil is better then no engine oil. But what specifications does your manual suggest? An oil with a high level of ZDDP would be beneficial in either a 10w30 or 10w40.

Minor correction
GP7500
T6 rotella synthetic not T5 (getting old memory not what it used to be)
Issue...Generac says synthetic 5-30 and T6 is 5-40. I have the T6 but I was afraid to use it because of the 40 instead of 30 and do not know if it makes a difference. If it does I will pick up mobile one 5-30. Sorry I just don't know how significant the difference is.

It would be Good to use, and the 40 will give you a little more protection in hot weather over a 30.
