I switched to full synthetic oil for 2024 in my sbc race engine and chose Maxima RS. I had used Brad Penn and Schaeffers prior, and had bought much on sale and even mixed the two when I went 10w30 using up what I had to the end last year. I purchased 9 gallons of Maxima RS during a sale last winter to try.

I sent out an oil sample of the Maxima RS 10w30 just to see what’s in the oil after 50+ runs and compare it to what I used prior because I’m curious. It appears Maxima has more Moly and Boron compared to what I used prior. The Copper is coming from the distributor drive gear.

This isn’t about what’s better oil, but thought one might be interested in results of 3 brands I’ve used after 50+ runs. I used Blackstone for the $35 oil report, and it took 17 business days after they received the sample to get the e-mail results.

not sure how to read all this but doesnt the maxima look pretty good

My sons ran Maxima oil in their SB Chevy circle track car then in their Top Dragster (alky) and their Top Sportsman (gas) cars.
