Redline 5w-30

[blackdiamond]

I just noticed that Redline is an SM oil so it would be acceptable under the factory warranty for my Mazdaspeed 3 with a 15.6 psi turbo.

Ignoring price, what are the positives and negatives for running Redline? I know the Polyol Ester base stocks (high temperature stability) are a positive, but not much else.

Hi, Redline does NOT meet any API requirements. It's also not SM rated, despite the label.

Positives: most shear stable oil on the market that is great for racing applications.

Negatives: price and poor extended drain capability. Doesn't seem to do well in all engines.

I actually inquired tonight with Redline to see if their oil was officially API certified or if it simply meets the requirements. I have no problem believing that it COULD be certified, but while I'm under warranty that isn't good enough.

No Redline, no Royal Purple, and no AMSoil.

Thanks for the info.

Actually it's Amsoil. What is with the "AMSoil" thing lately?

Anyhow - Amsoil does have have a fully API certified line: Amsoil XLF 5w30

The Redline SM thing is sorta like Amsoil in the old days. Great oil, could easily pass the performance tests, but too high P. At least the Amsoil PAO/Ester oil like ASL 5w30 meets the additive requirements of API SM.

Actually the Amsoil XL series oils are API certified, they are a grpIII synthetic. They work quite well in my Ford modular engine, but I can only go 6k on a change. The last couple used oil analysis showed that they sheared to a 10wt at 100C after 6k miles. Wear numbers where still good though. I have no expierience with RL or RP. I also get good wear numbers from MC Syn blend 5-20 and Pennzoil Platinum 5w20.

Chock it up to my ignorance.

No problem, I wasn't picking on you. It seems like it's a common mistake.

Probably has to do with the red color of the first half of the logo

Redline no good for extended drains? Define extended. I have seen and know people who use it for 10k drains. That may not qualify as extended for some, but its not like the stuff goes bad after 5k.

 

[Alcibiades]

There does seem to be wide variance among individual engines. Redline does not recommend drains exceeding 7500 if I remember right, which is its biggest disadvantage relative to price in my opinion. Best to do a used oil analysis around 5k and see what the numbers tell. I've had great results with it in both newer Honda (5W20) and older Toyota (10w and 5W30) motors.

Redline says 15K to 18K....which I think is too long and interval for my comfort level. I'd say the same about Amsoil.

I run Redline at 7K to 10K OCI...and the used oil analysis have been very good.

Redline is one of the only unique synthetics out there... their choice of basestocks gives them an edge for modified engines, or drivers who frequently or constantly utilize the full performance of their vehicles.

Red Line 5W30 is the best oil I've used period. Too expensive though for continual use in our Outback.

Why no RP? Royal Purple makes an API SM CERTIFIED 5w40 if you can find it.

 

[blackdiamond]

Owners manual only lists 5w30 so I'm not sure it would be worth it to track some down and "test" the warranty.

Basing Redline's effectiveness on engines torn down, or at least indecently exposed,compared to conventional oils Redline just plain rocks.Lotus and Saab turbo engines are in my list of frequently seen bottom ends. I have to admit ignorance about used oil analysis.
