Planning on going grade higher on the next oil change. Not sure either go 0w or 5w. As far as start up temp iím Not concerned as I live in TX. Looks like 5w has better NOACK compared to 0w so this is plus. What would you suggest folks?

That is 20 weight, not 30

Any 5w30 full synthetic you see at Walmart will do. dexos1 Gen2 is better, which many are going to anyway.

So you ran 20 weight all through the hot Texas summer but now with winter coming you want to switch to 30?
Can you share your logic with us? Are your cars using oil?

Prius manual says you can go to 5w-20 instead of 0W-20 assuming it is still fancy-pants oil in an emergency and only for one change. If it's that bad, why would they let you use it even once?

Go for 10w-30 for lowest NOACK. In TX 0, 5, 10w is all the same

Until upwards of 200K I'd be running 5w20 unless I was working the engine real hard, even in the heat. I've done recurring maintenance on four different J35A6/7's and with three of the four over 160K they give no feedback that the 5w20 I put in them is too thin.


To quote a friend, "Synthetics, man."

I think the OP has discovered there is a fuel dilution issue with one or both of his Hondas and a 30 weight oil might offset some of the viscosity dilution.

No need to seek for the logic. Just want to go higher on vis. Winter is not a concern, this is TEXAS

FD is definitely a concern. I also want to see if the engine will sound better - metal sound makes me aick

Good thing you spoke for him. Anything else you want to tell us about him?

Looks like weíre getting biased here. Ok, yes thereís fuel dilution, and yes I want to try to offset it some. Yes, engine sounds a bit [censored] to my taste, hope thicker oil will do better job with that regard. Thatís it. Back to initial question: would 0 or 5 make a difference? Personal previous experience supported by UOA is appreciated

I'd stick with 0W20 for your Honda. Try Pennzoil Platinum 0W20.

Except the UOA in question didn't show ANY fuel dilution...
