Hi everyone!
Little background: My Dad and I have a vintage race shop which takes care of primarily British vintage race cars, but I just bought myself a Datsun 240Z to hopefully have fun with now and then. It's a little out of our regular wheelhouse and I'm trying to be careful not to assume things about the Datsun based on my British experience. Engine oil is one of those things. We use Royal Purple 20W-50XPR in everything else and it's worked very well (though I wonder if there's anything lighter we could use in there...), but I'm not going assume it's good for the Datsun because of that. I'm happy to provide specifics of the Nissan L24 engine if that would help, but this car is used for vintage road racing and as such sees 7,000rpm regularly.
First off, I've taken some time to attempt due diligence and avoid starting a new thread. I wasn't able to find much experience with the specific oils shared with me, so I'm going to address them directly. After talking with someone who has a lot of experience and asking which oils are good choices for this engine, I was given a short list:
Amsoil AMO/Premium Protection 10W-40
Joe Gibbs 10W-40
Motul 300V 10W-40
Rotella T6 5W-40
I know how good Amsoil products generally are, and I know 300V is popular with bikes at least, and that Rotella has a sterling reputation for flat tappet folks.
I'd lean towards the Rotella for myself because it's significantly less expensive than everything else, and it appears to still have sufficient additives for an engine like the L24, but I couldn't find much about anyone using the oil for racing.
Does anyone have experience racing any of these oils, or a link to info of that sort?
Thanks!
Mike
