Makes sense to me. Todays oils are leaps and bounds better than the oils pre 1990's. Regardless of weights they last much longer, manaufactuers are suggesting much longer oil change intervals as a result, for instance no longer every 3k miles...but now 7-10k and in some cases even more. WTF?! Now whether us old cats will ever trust those recommendations because we've been conditioned otherwise or not is another debate. Certainly I don't, BUT it illustrates there is a difference in today's manufacturing of oil compared to yester-year mainly to reduce consumption of said oils from excessive oil change intervals.

Moral of the story....stick to the manufacturer's suggested weights, and be good about your change intervals and use quality filters....that fellow sirs, is where the anchor lies....:daz:

I agree. Not only the oil formulations, but generally, todays production engines run so much cleaner. Just about any modern day vehicle, you can pull a set of plugs at 75k miles, and they look good. Unlike the cars of yesteryear, you were nuts if you tried getting 75k miles out of a set of plugs in a 1970 impala! The oil nowadays isn't getting diluted and contaminated with gasoline, combustion deposits, etc.

Although, my blown carb'd boat engines aren't exactly new technology. They still fall under the "must change frequently" rule because of contamination. :bunnydance:

Yes, I might even throw a quart of the purple oil in my in my pressure washer and see if I can get a few extra psi out of that b*&ch :evilb:

Excellent idea. Hey it was fun. Killed some time. Have a safe and fun season.

Joe,
Can you tell me what Oil I should run in my 300's? The current oil I run seems to smoke some
at cold start up. I need an oil that likes to run at high rpm's :)

Lots of guys run the VR1 dino oil. Its good stuff.

A couple weeks ago autozone had Kendall GT 20w50 on sale for 3 bucks a quart. Teague sells it for 4.59, which is still a good price. MY buddy bought a few cases from autozone. My zip code is showing 3.49 a qt now

ok, so a NHRA team who qualifies first, is sponsored by Royal purple. Forget the oil lab analysis', technical data, and how the oil actually performs. Im switching to Royal Purple!! Maybe this year I can be first place in the poker run!

I place no trust in anything related to nascar, nhra, or any kind of sponsored sport. Theres more politics in that than in Chicago's city hall.

Did I mention Burger King has the BEST burgers??? Its all I eat. Here's why.

I don't post much....but that was funny.

Okay, I just read this whole thread! Yikes!

So simple question, what is the best oil for our marine engines?

I know this is an older thread but I was researching oils for my Formula 382 fastech w/ 600 sci motors. Where did you find the load carrying capacity/film strength for those oils? I was planning on running Valvoline VR1 20w50 since thats what i already run in my big block nitrous drag race motors but did not see that specific oil in your film strength rankings on page 1 of this thread. Can you point me in the direction of some current info or atleast the load carrying capacity/film strength of Valvoline VR1 20w50 conventional race oil (silver)

Thanks,
Southernhick
