Cobra Owners Preferred Engine Oil Brand?

[AL427SBF]

mpanten, that is one but HR-2 looks like a better fit maybe? I'm not a big block, or blown, or have loose bearing clearances.

HR-1
15W-50

• STORAGE PROTECTION
Uses the same oil additive technology developed for the U.S.
Military for storing and shipping their combat equipment.
Protects against rust and corrosion so your engine is protected
even when it’s not running.

• HIGH ZINC CONTENT
Higher levels of Zinc (ZDDP) than regular passenger car oils.
Delivers proper anti-wear protection for older style push-rod
and flat-tappet engines.

• CAMSHAFT WEAR PROTECTION
Superior camshaft wear protection chemistry. The same wear protection found in Joe Gibbs Driven Racing Oil which has powered Joe Gibbs Racing to multiple NASCAR Championships.

Applications:
• Perfect for big block muscle cars and blown street rods. Excellent high temperature protection. Good for loose bearing clearances.


HR-2
10W-30

• STORAGE PROTECTION
Uses the same oil additive technology developed for the U.S.
Military for storing and shipping their combat equipment.
Protects against rust and corrosion so your engine is protected
even when it’s not running.

• HIGH ZINC CONTENT
Higher levels of Zinc (ZDDP) than regular passenger car oils.
Delivers proper anti-wear protection for older style push-rod
and flat-tappet engines.

• CAMSHAFT WEAR PROTECTION
Superior camshaft wear protection chemistry. The same wear protection found in Joe Gibbs Driven Racing Oil which has powered Joe Gibbs Racing to multiple NASCAR Championships.

Applications:
• Great for small block engines and "crate" motors.
• 10W Multi-Grade formula provides excellent start-up protection.

I think either would be good. The guy i talked to did mention that the small block windsors like yours and mine tend to suffer from low idle oil pressure. I was running 15/40 diesel before so i was pretty close to what I was running. I would not be afraid to run either. He also mentioned that the aluminum tends to expand and contract a little more and the heavier weight would be helpful.

This has probably been covered before, but is there any issue with mixing different weight oils of the same brand?

No not at all (assuming we are talking the same brand and same product line).
