I was most impressed with your creatively phonetic spelling of "original", (or-ig-in-le)


...as a side note, what do you think of using Redline 5-30??

Redline makes fine oils in general, but in regards to our engines they're not the best match as they all tend to be either too thin or too thick. The Kv100 of the 5W-30 is just 10.6 cSt and the oil that actually get's closest to the BMW operating viscosity range (albeit on the high side) is the 10W-40 with a Kv100 of 14.6 cSt.

The Kv issue notwithstanding (although VERY important for LL adherence), I personally think the RL engine oils are overpriced or OUR use. They are POE grp. V base oils, which are much more expensive to manufacture over grp. III GTLs and most grp. IV POAs. Plus they use very expensive (albeit robust) additive packages that are designed with an eye towards harsh engine environments such as forced induction and alcohol fuels (methanol, nitro etc.)

When I used them in 2 different vehicles (regular street use), both had higher ppm of lead in analysis. My tribologist surmised that the add pack may have had some reaction with bearing overlays that caused this. Same fuels, same routine driving etc., so nothing out of the ordinary, other than the RL. Switched to different oil and the Pb steadily dropped over a few K back to average levels.

Not the first time I've heard that RLs chemistry may be a bit "extreme" for other than high-stressed use. Don't get me wrong, they make awesome lubricants, just might not be the best "fit" for us IMHO.

Use any of the 3 popular choices (BMW/Castrol dealer oil, Castrol 0W-30, Mobil 1 0W-40) and you'll be good not only in the sump, but in the wallet too over the RedLine stuff.

Hi Everybody,

The info on motor oil is great!

Help me (2001 325I) out if you can as for those of us living in this part of the world (tropical Asia) do you think we need rating of 0W or 5W at all since climate is always 20 degress celsius being the coolest in anytime during the year?? Shell Helix Plus 10W-40 seems to be adequate as the local garage is advising me. What do you all think?

Even at 20 C, a 0w oil is going to be thicker than the engine needs it to be. So by running a 0w-40, you are still going to see benefits when you are starting up a "cold" engine.

Simple. Any one of these three:

BMW High Performance Synthetic 5W-30 (get at the dealer or OEM parts site sponsor)
Castrol Syntec 0W-30 (Available at AutoZone. Look for "European Formula" and Made in Germany" labeling)
Mobil 1 0W-40

Don't deviate or second guess this. It'll start another oil war thread .

Just changed my today... it's been 7k miles since last time when I used Castrol Syntec 5w-30. This time I used the new Castrol Edge 5w-30. I've always ran Castrol and it's never done me wrong so I'm gonna stick with them.

I'm thinking about blending my own oil for my next oil change.

I'm going to start with two parts of the Redline stuff that is a little too thick, added to one part of the thin Mobil 1 5w-30.

Maybe even bottle it and sell it.

I'll need a name for it....

Bun's BMW Brew.... Triple B .....

Oh, and I'll need an advertising slogan....

Why settle for LL (Double L) when you can have Triple B.....

Castrol and Mobil 5w-30 or 0w-40 or BMW 5w-30 have a very close Physical and chemical properties, so for normal type of driving it doesn't matter. I know a person who is using same Castrol 5w-30 since he bought a brand new BMW 323i and have 150,000 miles and don't have any problem what so ever with the engine.
It's all BMW myth, to make people buy their staff, then Mobil and all others did came up with same Physical and chemical properties as BMW oil. BMW oil is probably made it by Castrol.

They are not close in spec. HTHS on the 5W30 is way to low and in an engine that is noted for shearing that's a real dumb choice. To many posts with sludged engines on all the BMW forums and to a man they all used the wrong oil.
