No definitive answer, it's all based on your use-case, circumstances, and OCI. I've used BMW 0w-30, Castrol Edge 0w-40, and now Motul Xcess 5w-40. To me the short answer for best bang for the buck is Castrol 0w-40. Very easy and cheap to get (at Walmart) with good wear/sheer properties for its price/accessibility. BMW oil used to be made by Castrol, then BMW moved away, and now they've come back to Castrol. My concern is really just engine wear - so the oils I like to use in relative terms will be better for that.

Wouldnt best bang for the buck then be Liqui Moly 5w-40 leichtlauf from FCP euro and taking advantage of their replacement program? I mention the leichtlauf specifically since they only carry a handful of oils and seems like it could be the better of the bunch.

But Castrol Edge 0W40 is exceptional oil and category that Liqui Moly is not playing in.
That is why it is best bang for a buck.

Honestly, you can't go wrong with OEM BMW oil for normal conditions.

I went with Liqui Moly because of FCPEuro lifetime replacement.

Anyone with experience using Castrol Edge 5w30? Looks like it's the only LL-01 from Castrol. I was using Edge 0w40 before, but that has lost it's LL-01 approval.

0w-40 over 5w-30 hands down.

Pour point on the 0w-40 is -57 vs -36.

Viscosity index on the 0w-40 is 181 vs 165.

This tells me 0w-40 contains a superior base stock compared to the LL-01 5w-30.

5W30 is 100% Group III. Lot if short branch polymers.
0W40 is 50% PAO, star like polymers = more shear stability.

I've being using Mobil 1 5w50 for my track days. It works really well!

Two questions for you.
Is castrol edge 0W-40 and 5w-40 the same formula from a user standpoint just different weights? Or one actually has better much properties than the other?

Second question, in warm regions where winters have little impact (Florida) is 0W-40 castrol edge still the go to? Or should I be running 5W- 40

5w-40 is LL-01 approved whereas 0w-40 is not.

0w-40 is still superior compared to the 5w-40 since it's slightly thicker at 100c, but we are splitting hairs at this point.

I would feel confident running either in any climate except say Russia in the winter haha

I'd like to see Edycol's reply on this.
He's the Wizard of Oilz.

edycol,
Could not find any mention of Amsoil in your posts. You position?

Lol guys, I was skiing few days with help of this single malt: [IMG][/IMG]
So, 0W30 and thicker brother, 0W40 are Castrol's premier products.
5W40 is strictly Group III product, basically made to "muddle" through all the approvals. I would put in in rank of Liqui Moly etc.
0W30 and 0W40 are 50% PAO based oils. Extremely shear stable for its viscosity which means some stout polymers and not too many improvers (especially 0W30).
Pour point in these oils is indicator that they are PAO based. Group III oils such as Castrol 5W40 are usually having pour point between-39 to -45. PAO based oils have very, very low pour point. As stated in Castrol 0W30/40 pds it is around-60. But one might ask: ok, I am in Florida, so who cares about pour point? True! Actually pour point is irrelevant unless in Siberia, Fairbanks, AK. But, it is gives us insight about base oil. PAO is stout, shear stable, provides higher HTHS out of similar KV100.
IMO, N/S55 engines, Castrol Edge 0W40 is way to go for daily, occasionally on track.

It is very good product. But IMO, waste of money. Not better or worse than premium products from Castrol, Mobil1 etc. They have several gear products that are very well regarded like Severe gear etc.

[SE7EN335]

If you want to use a 5w40, I would go for Shell Helix/Pennozoil Euro 5w40 over any other oil because its a much higher quality base stock Group III oil (on par with PAO Group IV oils)

I personally use 5W40 Shell Helix for daily and for track, Mobil 1 5w50.

[FrankMstein]

Thanks, been using it for almost 20 years and have seen that and other videos on it.

What about Redline oil for daily driving / occasional track?

Problem with Redline is oxidation. High ester content is probe to higher oxidation. So you must keel OCI in check.
I like a lot of their products(I use D4 in my E90 manual gearbox). But not sure engine oil is worth extra buck unless serious modifications or some competition. If just occasionally going to track, again, Castrol 0W40.

Don't go so heavy on track if no modifications that shear down oil. Don't forget, heavier oil creates more heat, takes away performance. If you are completely stock, you are doing more harm than good.

5w-40 does not seem to heave though. I have been running liqui moly 5w-40 for about 20k miles now

I am talking 5W50 on track.
Liqui Moly is average. OK, but nothing more. Too heavy (don't forget 40 grade is range) for HTHS it offers. That means group III base stock.
