Best Oil for my car

e90dum · 12-02-2016, 09:39 AM

Hey all, I've been putting nothing but mobil 1 0w-40 in my car because wallmart has a great price on it but i learned that it isn't on the bmw ll-01 list because the formula changed (or maybe bmws turbos want something better or something)

I'm currently chasing an oil leak and am about to change my oil again(and will use mobil 1 because of the cost until I find the leak) but should I be using something better? Is there a "better oil" or am I stupid for even worrying about it

IMO, theres nothing wrong with what you are using.

certainly not. Mobil 1 is poor quality performance oil. use motul or castrol syntec 5w-30. if you run it hard, don't hesitate to upgrade to 5w-40 oil

I run it pretty damn hard, but I want to put the right stuff in my car...

Motul, Amsoil, castrol. 5w-40. no exceptions. Mobil 1 is not protecting your engine. especially not 0 weight.

And I'm good to use 5w-40 vs 0w-40? I don't know shit about engine oils and I don't want to fuck my stuff up because someone on a forum told me to

sprp85 · 12-02-2016, 02:44 PM

0w-40 castrol edge (Euro spec)

N52 engine manual specifies that 5w30 or 5w40 is suitable for all weather conditions. since you drive it hard, 5W40 NO EXCEPTIONS!

Its not enough to leak a half quart of oil, but does this look 'broke to ya'll

Go read on some UOA's.
The euro formula castrol is not the greatest, as it sheers down a full weight in oil within 2k miles. You want an oil with high zddp content to protect the motor during hard use. That said, all street automobile oils must meet specific regulations and as such, there is a limit on how much zddp can be used, as it burns out the cat more quickly. You need to look to other oils, such as ones specified for racing or even truck oils.

A popular and well known oil with high zddp content, 5w40 group 4 synthetic is Shell Rotella T6. Many track guys run it, and this oil holds up to the abuse. It is high in detergents (it is meant for a diesel engine!), but also is highly resistant to sheering (read: it retains it's 40 weight longer, despite use in elevated engine temps)..it also does not need to confine to an automobile specific regulation for zddp content, as it is a truck oil. I use this in all my track cars which require a 5w30 or 5w40 oil.

Aside from that, I've had tremendous luck with Redline. This is an ester based oil (group 5), so is a little different, but also doesn't need to confine to the same regulations as standard car oils. It's good stuff, though more expensive.

uh, do you understand SAE ratings at all? 0W40 is not a "zero weight" oil. the first number refers to how well it pours when cold - it has nothing to do with protecting your engine under load, but it does protect it better when the oil is cold and getting it pumped everywhere when you first start the engine. Otherwise, it's no different than a 5W40.

boro92 · 12-02-2016, 03:48 PM

And for what it's worth, Ferrari's are spec'd with 0w40 oil. To Hassmaschine's point, there is nothing wrong with a 0. It only denotes the viscosity of the oil before it reaches operating temp.

This.... m1 ow-40 is an excellent oil for these engines. in my case it even calms down the lifter tick i get during winter when i don't drive the car as often or as hard as i ought to.... over the couple of castrol fills its had anyways.

Also, if you're not sure go here - www.bobistheoilguy.com

great resource like e90post to do some research, but it's all about oil and lubrication instead of e9x cars.

I've actually noticed the weight of my castrol 5w-40 sheer down to 30, you are right about that. I think motul or AMSoil is probably the best. but castrol is better then Mobil 1, so i can only imagine how bad M1 is. its a very watery oil. if you guys think your engine sounds healthy and quiets down the lifters with 0w-40 M1, you have not seen what a proper 5w-40 will do at operating temp.

And FWIW I use 5w40 shell rotella

The old M1 formulations were poo after that whole lawsuit they got into with Castrol marketing semi-synthetics as true synthetics. When they lost, they also dropped down to semi-synthetic formulas. However, their 0w40 is a true synth. It isn't a bad oil. Nor is it fantastic however. For street use, I wouldn't be to worried.

its definitely fine for street use, but running 0w-40 weight with M1 will do nothing good for your engine if you drive it hard

It won't do anything bad either.

Make sure it has "European" label on it, that is the Castrol Made in Germany and LL01. Or you can look at the specs on the back.

bimmerquick43321 · 12-03-2016, 10:26 AM

I'm sold to Castrol and very frequent oil changes, never had a engine failure with any of my cars no matter how hard I beat on them and me or mechanics that work on the car are always impressed how clean the engine is when let's say changing the vcg, also when I have oil leaks seems to leak less with the Castrol versus other oil of same weight, so yeah as I said I'm sold to Castrol lol
