No, no, no. Nomex socks only!

Not quite sure what kind of racing oil you guys are talking about but the post and picture of the label on the driven [Joe Gibbs Racing Oil] Says it all read it

I would avoid additives. Research I've read says can do more harm than good. I went to Amsoil Z Rod. High zinc and made for the application. Not cheap, but good stuff.

whats the API ratting on that oil

fjd

Nice, what weight are u using?

Wayne88

I do my own oil changes, and the price for Mobile 1 [on my C6], is around the same price as Valvoline with zinc added [on my C2].
The price of the oil change should be about the same, either way.

fjd

Corvette Paramedics in NJ charges about $165 for an oil change for a C2 with the zinc additive.

jim lockwood

That's absurd.

fjd

That's what I thought. I dont want to pay that, its more than I pay Audi to do my RS5 oil change.

So just to wrap, consensus is:

1. You need something or not? Zddp?
2. Use Rotella or use Valvoline with zinc or Amsoil Z rod, Hot Rod Motor Oil with Zinc, Brad Penn Oil?

Amsoil talks about protecting older cars but their web site doesnt go back to 63.

What is the consensus if I do this myself? Many answers here.

Thanks

Go to a store find a oil with a. API ratting of CK-4. Buy five quarts or six depending what oil pan you got. That’s roughly 4.50 a quart. Then get a filter. You should have no more then 35 dollars in a oil change

fjd

Weight?

Nowhere Man

10w-30 should be good unless your driving in sub zero temps

jim lockwood

See the very first reply to your question in posting #2. It is the correct answer.

jim lockwood

There are four things to take away from the discussion of oil for our older engines:

1. If the engine has stock valve train, meaning stamped steel rocker arms and a flat tappet cam, the engine needs oil with ZDDP

2. There is such a thing as too much ZDDP. In excess quantities it causes an obscure and poorly understood form of internal corrosion.

3. Racing oil has appropriate levels of ZDDP but it lacks other ingredients needed by street driven engines.

4. Diesel oil has appropriate levels of ZDDP and is inexpensive.

Great which Diesel, Rotella with c4? What weight? Thanks!

Look on the back of the oil bottle and look for the API service ratting of CK-4. Brand does not matter. Marketing hype has nothing to do with the API and SAE ratings

jim lockwood

I use 15w40 which is good down to temperatures at which I have no interest in driving my old cars. Rotella is fine but don't obsess over brand.

Go back to post #28. Follow the instructions in the first paragraph. The oil article will answer all your current questions, AND all the ones you haven't gotten around to asking yet.

II had to go back to post 28. I hadn't read it. "Whale Sperm" is deceptive....the old whale oil used in oil lamps for illumination and later, in the petroleum industry for fine quality lubrication needs actually came from the sperm whale, which has a huge waxy deposit of fat containing this oil in it's forehead. The finest stuff available in the natural world. So the oil isn't 'whale sperm', wasn't named that because it was expensive later on, but because it did, in fact, come from the waxy forehead deposits of sperm whales.

Gloves help a lot on a hot day when things get sweaty and slippery. Grip on the steering wheel and shift **** is nice to have! Not everybody has AC in our midyears.....
