No i use many oil brands in my builds one of them are Valvoline vr-1 . Never had any problems with that oil.

I made a mistake with too tight bearing clearances and the 10-60 valvoline didnt help in that situation. Renault f7r engine on a rally (endurance) aplication it keeps the oil press higher than example castrol 10-60 oil.

What engine damage are you referring to? Where are you hearing this?

I flog the sh*t out of my deal on VR-1. I do oil analysis each oil & filter change, no problems here.

Yes, Valovoline VR1 is the Chicom knockoff being flogged at a bargain price on AliExpress; it can be recognized by the intentional misspelling of the brand name to get around international copywrite laws and that it arrives in a case of 23 bottles.

On facebook about 3 weeks back, someone did a write up of how VR1 absolutely was the cause of an engine failure. I can't for the life of me remember who wrote it, BUT they were a reputable name. Not some internet troll. I've done a couple searches for it, but I cant find the post. That's why I asked. It was a pretty well known name in the industry. I'm shocked noone on here has heard of the post. I'll continue to look and see if I can find it. I only use VR1, so I hope its nothing.

Just some old graph about different oils. Left to right duration of surface pressure, scratch mark and load time. I can pm full 42 page summary, if any interested, but its writtin in Finnish..rewguy wrote: ↑Tue Aug 02, 2022 10:47 pm On facebook about 3 weeks back, someone did a write up of how VR1 absolutely was the cause of an engine failure.

and see back then if it was "Valvoline VR1 ???" ... it was brand new type Valvoline back then when we tested it
here's the SpeedTalk Link :

Re: is Valovoline VR-1 really hurting engines?
Yea the VR1 can be anything between engine oil to brake fluid... Anyway the comparison i was referring to had this VR1, and they found better oils. Sorry about foggy pictures,

Scar testing is mostly irrelevant to engine oils. It can give it indication of additive response but that's about it. It's highly sensitive to phosphorus which can skew results. It's easily manipulated and very difficult to get repeating results with the same oil. For example, I could put a bunch of tricresyl phosphate (TCP) in the oil and scar test it, it'll show an excellent scar result. However, a flat tappet lifter would chew itself up in seconds on that. It can't provide an anti-wear function in the real world.
The thin oils used by NASCAR cup engines and Pro Stock engines produces a rather large scar in those tests, yet those engines very rarely have wear problems. You can add non-P anti-wear and friction reducing additives like molybdenum dithiocarbonate (MoDTC) and moly-sulfur complex that'll synergize with ZDDP to boost anti-wear function in an engine, but won't move the needle in a scar rig.
What a scar rig shows and what actual engine data shows, the data more often than not doesn't reflect each other.

Not related to the VR-1 specifically,
But the LS boys are many and all around, and the LS running stock lifters, doesn’t seem to like any weight oil above zero weight.
I had a guy recently going bananas over lifter ticking that was cured by going from VR-1 10w60 to thinner oil.
