Pull the pan when the engine is still hot/warm and you won't see that. High zinc oils (over 1,000 ppm) will precipitate additives when the oil is cold. -Al

So 5-8 hp from 10w30 to no oil ! Is it really worth any hp, from 10w30 to 0w5 LOL .we all do it ,but.......

Oil helps the rings seal , without any maybe you would lose power from that and offset the gains from low oil pressure .

Looking for Opinions / Experiences on the differences between using Valvoline VR 10w-30 Synthetic-Blend vs Valvoline VR 10w-30 "Full Synthetic" motor oil?

Specifically with respect to ring wear?

I had really good luck with the full synthetic Valvoline racing oil. Cant seem to find it anymore at the local parts stores.

I've been really happy with JR-1

You may want to look at Reher-Morrision tech tips on oil and filters, oit of 100 tips they are toward the end (95 & up as I recall) Filter tip very interesting

One thing they told me was to try Bad *** oil, I believe the originator of the early good Royal Purple.

FWIW

This might be true Alan, but I don't see the same amount in the pan after switching to Brad Penn, which has no moly. If I convince myself that the VR1 has better wear numbers, I'll gladly live with some goop in the pan.

The question that I can't seem to get a decent answer to is why so many racers use multi weight oil instead of straight weight.

May I ask the part number of the Valvoline oil you refer to?
I have used the VV850 in the past but they no longer offer it.
I believe they changed the formulation.

Do you use an additive with the oil?

The oil I used is straight 30 racing oil. It used to be commonly called VV223 but the Valvoline part number is 822401. Scroll down a little to find Valvoline's conventional oil part numbers, https://www.valvoline.com/our-produc...vr1-racing-oil

I don't use any oil additives.

don't use either.

Been running Mobil 1 Synthetic 10w-30 in my race engines for nearly 3 decades.

This past season switched to Lucas Synthetic. Have a case of Maxima Synthetic that I will run this season.
