Is Red Line 0w40 worth it over or Castrol 0w40 or Mobil 1 0w40

That's not necessarily a problem. Whether it is depends on how high the wear numbers are, what the bearing materials in the engine are made of, whether it has a copper oil cooler, and prior UOA history.

As for lasting longer than those other two oils, I doubt it. Those oils meet very demanding oil specifications designed for long oil change intervals.


Great points.

Russian link-skills... Sorry.
You must navigate to "Laboranalysen", "Motoröl->Frischöl" und search for Redline 0w-40

edit:
To "ester based" guys. We have a thread about it

I use RL 0w40 all year round in my Z3 with 2.5 I6. It loves it.
also use RL 0w40 in winter in my e46 330i

Soooooo I suspected I needed a valve cover gasket This morning. Needed an oil change anyways....
Smelled a bit of oil on exhaust manifold-
my Z3 with 50,000 miles. It's a 2000.

I've been using Redline in the car since I got it with 32k on the clock
My mechanic said he never ever sees the valve train so clean at this mileage
as new
(I'll post pics later)

Very high quality, shear stable VII's.


Do you know that or are you guessing? I have seen it stated by others as fact that most RL products contain no VIIs.


Their race oils don't, but their street oils do. The 0w40 has a lot of VII's, and the last time I checked, its temporary shear ratio was not as good as M1 0w40.

And so Red Line oil contain high lead? is it bad for Exhaust system?

 

[Cheburashka]

Found on Red Line website interesting info about 5w40
Thicker oil film at operating temperature than a petroleum 20W50

It's RedLine 0w40 if you jump to page 3 you will see it.

So could you share the OCI been used?

Where did you get your redline composition information?

 

[330indy]

Redline 0w40 since acquiring the car with 32k miles as an 18 year old car. It super-cleaned it up after four OCIs with Redline. Now at about 50k miles, average interval is 4K
So clean
Redline is the stuff

It's been said many times on BITOG over the years.

Redline is overkill for anything that's not a track car, imo.

 

[330indy]

It's not overkill for my valued not-inexpensive cars (BMWs)

Well maybe what is the documented tangible that its going to give your BMW over lets say a cheaper oil like QSUD?

And I've seen it stated otherwise. So which is right? Maybe it doesn't matter.

Impressive pics. Redline motor oil certainly keeps engines clean. But, at a cost. I rather purchase Redline oil than a bottle of alcohol. Priorities!

 

[330indy]

me too. (regarding the priority over booze, LOL)
I go extended OCIs (by time) in a couple garage queens with 100% confidence
