The summary of the conversation is that any racing specific motor oil will have the z/p levels we are looking for. it makes sense that racing engines require the wear resistance, as well as the bigger issue of not being concerned w/ catalytic converter damage. i can only speak for the valvoline products (which i use in all my vehicles) there VR1 racing oil, conventional and synthetic, would be a good oil for our motors. it has detergent levels that work well and even for a racing oil affords a conventional 3 mos 3,000 mi. oil change. The reps explained that the "not legal for street use" oils are for higher horsepowers, have very low detergent, and only have a 500 mi oil change recommendation. so that is my $.02 on oil for those who are interested. i do not work for, or am not promoting Valvoline products. The info and the link are for informational purposes only. The link will take you to the Valvoline racing oil info page. Hope all of this is ok with everyone on the site. big ed http://www.valvoline.com/products/consumer-products/motor-oil/racing-motor-oil/

The advertise some of the pro and con compared to racing oil and diesel oil. Eastwood sells it as well as a few others for $10 (4 oz) used per 4 or 5 quarts. For comparison Jegs sells that ZR-1 racing oil at $12 per quart. More $0.02 to consider.

I use to just buy a quart of EOS from Chevy Dealer and go from there. Well, just recently my nephew went there looking for a quart for a fresh 235 engine and they didn't have it.... but had a couple other little bottles for about 8 bucks for a small bottle.
I guess selling a small amount for 8 bucks vs 5 for a quart is good business.... for them! | | | | | Joined: Dec 2006 Posts: 165 'Bolter | | 'Bolter Joined: Dec 2006 Posts: 165 | Patricks engines in Arizona also says VR1 Valvoline oil is his choice for older engines expecially after a rebuild. I have used it with no problems at all. Pretty pricey for oil, but then again what isn't.

If you don't want to pay extra for 30-weight synthetic HDEOs, conventional 10W-30 HDEOs cost less than racing oils and provide better sludge protection to street-driven engines.
