Ok to use 5w during summer?
 

Since the oil is 40 viscosity, it shouldnt matter at operating temps. Advance has the Rotella T6 5w-40 thats the same no conservative and has JASO approvals.

I have been using it in my priller for about 30k miles now and no issues.

Im going to be putting it in my VFR.

Rotella is what I used in the 600 and what I use in the DRZ and CRF.

Just have ot make sure its the dark blue bottle and is the T6

yep, the synthetic 5w-40 stuff. I don't remember the T number, just the 5w-40 syn in the blue bottle.

that's what I run in mine....

I had some concerns in th epriller being its a twin but several guys us eit an done is in arizona with over 100k on the clock so I guess it cant be too bad running in th eheat they have down there.

Ive ran the 15w-40 triple protection with no problems. Never could find the T6 and Advance finally carries it. The T5 comes in 10-30w and is semiblend. I have that in my vehicle right meow.

I run Rotella 5w-40 in my car and two bikes.. love that oil.. relatively cheap and always scores really high on tests.
