Best Dyno Oil??

[mkgarrison5]

hey guys, if you only could put dyno oil in your motors what would you go with and WHY?? my family has been using Havoline since the 40's-50's.. no seized motors to this day.. with all this talk about how synthetics may not be synthetics i figured i would start a dyno oil post and see who uses what and why

thanks fellas

I usually stick to Valvoline, Pennzoil, or Quaker State. But as long as they've got the ASE symbol on the bottle and you change the oil every 3-5k miles (I change mine at 3500-4000), you won't have any problems no matter what brand it is. I don't think anybody has had a motor seize up on them using oil from a reputable oil company (with regular changes, of course).

I use Valvoline, because that's what the Toyota dealerships use around here.

I've always used Quaker State, Castrol or Valvoline myself too (usually whatever I can get a cheap case of at Costco), but I have even tried some of the very cheap oils and they seem to do fine too as long as you change them often to limit any chance of sludge buildup.

I've certainly used it in the past, but I don't see it much up here at all.

I would say Valvoline....especially the Max Life oil.

I've been using Castrol high mileage since about 80k and it's worked good for me.

For dyno, I use Valvoline.
The only vehicle I use dyno in is the 89 Pickup.
The Tundra and Celica only get Mobil 1 Syn.

i read on BITOG that valvoline high mileage dino is good, castrol gtx is good, and penzoil are good in the yotas

Valvoline, hands down, no exceptions.
