Classic Nautiques

I know everyone has their favorite oil, and I agree that you need ZDDP. I am not trying to be disagreeable or dismiss Gary or Pete's advice, they, and others here, are Correct Craft experts, something I am not.
Oil analysis shows Valvoline VR-1 to have 1200 to 1300 PPM of ZDDP. I am sure it is good oil, and it is the least difficult to find.
I prefer and use Redline 40WT (15W40) race oil in my old Willys and some of my friends vehicles with antique flat tappet engines. At 2500 PPM of Phosphorus and 2400 PPM of Zinc, it has twice as much ZDDP as Valvoline VR-1. Although probably not necessary, I will use it in my Mustang (1970 Ford 302) when I finish it this summer. Remember, most racing motor oils have less detergent and require more frequent oil changes than "regular" motor oil, Valvoline VR-1 and Redline included. With their reduced level of detergent, the oils will not keep contaminants in suspension as well as conventional oils.

Not true. Vr1 does not have lower detergent levels than "regular" oil. Only valvolines traditional race oil (blue bottle) has the lower detergent package.

I'm not smart enough to know what level of zddp would be considered "too much"... But 2x the levels in what we consider to be adequate certainly would have me looking for the answer to that question.

I was bored and had forgotten the reason for a maximum of about 2,500 PPM of ZDDP. I did a little checking and found that above that concentration the ZDDP will no longer remain in solution in motor oil and "falls out".

Here's the motor oil I use.   And it costs less.
And it has the Peace Sign right there on the bottle!





Peace Out!!!

Have a wonderful Christmas Billy. I hope you and your family are well and can enjoy some time together. Best wishes for the new year! Catch you next time.

The Valvoline VR1 Racing & "Not Street Legal" racing oils contain additional additives for increased horsepower and reduced friction on metal parts, provide extra wear protection for high compression/higher horsepower engines, and include fewer detergents than regular conventional motor oils".

Youre right, I misspoke. The VR1 does have a slightly lower detergent package than their regular oils (this reduces the oil's tendency to foam at higher RPM). Based on the conversation I had with one of their techs a few years ago, along with what Im reading on the web, the VR1 still has a healthy detergent package... and I dont see any official word from Valvoline that recommends a shortened oil change interval due to the lack of detergents.

Their off road racing oil (blue bottle) on the other hand, is a non-detergent oil that comes with a 500 mile oil change interval, last time I checked. Its unfortunate that they lump the 2 oils together in that statement, as they are 2 very different products.

I dont know why Valvoline has taken their product spec sheets off the web and replaced it with a FAQ section with marginal value. Id rather get the word from the engineers than from the marketing team... this is one of the reasons Ive been using Mobil1 15w50 more and more often. That, and the cost of VR1 has crept up to the point where they cost about the same.

Hey, Dr. They aint got nuthin on this oil. Nothing but the best for my CC.

OMG You guys are killing me!

And rear ends!

Now I understand why gear lube has an unpleasant odor.
