whats the best oil for my M45s?

[The Bodyguard]

Ok so my oil change is due I have 42k on the odo. Want a better oil opting for synthetic (mobile 1) maybe..... What are you guys using and how is it performing? Also how often do you do oil changes on synthetic for an everyday driver?

I use the cheap stuff, but I do it often tho, like every 1000 miles.

Hey Doc Antz, if you're bugging out about me and my oil changing routine on regular oil, which is not exactly at the 1000th mile anyways, you would probably choke some of my friends and they're stupidity... err, point of views on this subject. Some of the Audi guys swear oaths to use the most expesive and fancy full synthetic oil blend they can get their hands on, along with K&N oil filters and all that expensive stuff... every 1,500 miles, like clockwork, no b.s. I think this behavior has to do with Audi/VW having an engine that's pretty known for oil coking, that engine is called 1.8T (4 inline cylinders) and there has been numerous horror stories with those.

On the other hand some of my JDM friends (ricers) lol, feel like they have to keep up with the EURO guys in order to not be discriminated against and be called ricers so they also follow this... nah, j/k, the ricers just dont know what to do with their life savings and their minimum wage checks.

On a real note though, my biker friends, in my opinion, are the only ones that have a good point to change the oil frequently (1,000 miles) and with semi or full synthetic blend of oil, given that they ride their crotchrockets hard though, and I dont mean for the regular guy on a cruiser to change his oil so frequent. We run bikes at very high RPMs for long periods of time because they're designed to be driven that way and you can just imagine the goo paste these engines, at that temperature, would make out of regular oil. So the reason I do this on my car is habit.

My wife's truck gets oil changes by the mile intervals that the PMCS book says to follow which is 5,000 miles on regular oil, according to Lincoln/Ford. I feel pretty confident without doing any oil analysis, that my car's engine is in good "oil" shape, and it doesnt hurt my pocket to do a cheap oil change monthly. I know you mentioned that you've never seen an engine damaged by oil issues but I have, cornballs and women get affected by this year round. To this day I tell people that when I owned BMW's they paid for oil changes up to 50k miles and that they (BMW) used to do them 15k miles apart and they usually dont believe me. But as soon as I tell them they used Castrol Ultra Synthetic F1 GP blend, that costs $80 a quart, they go like "Oh, that's why man, that's that good sh*t" and of course there's no such such blend, it was just plain full synthetic Castrol, but people tend to think that because they're paying extra (getting overcharged) for stuff, that they must be getting the good stuff.

That's why I didnt opine on the Blackstone labs thread, everybody is free to do as they wish with their money and if you think you're getting your money's worth by sending your samples to them, I will be the first to attest there's no better feeling, especially if you're trying to figure out when you "should" change your oil. I stick to my el cheapo oil routine and change it monthly before it breaks down, because that works for me.

How "cheap"?

Yes, fresh oil is good oil, but if you use a good dino, you can easily stretch to a 3750 mile OCI without any issues. Something like Chevron Supreme or Castrol GTX (in a 5W-30) will be perfectly fine to do.

Right, I mean cheap like I dont do sythetic or semi, not like I use autozone brand. I do valvoline.

[antzrus]

OK, OK Blanco & szh. And I bet you guys have plastic slipcovers on your seats too...

My slip covers are very expensive ... I use Mobil 1 0W-40 and change the oil and filter every 3750 miles (probably overkill too).

I currently run on 5w/30 from Castrol. I was interested in synthetic and maybe go longer between oil changes like 5k... I do a regular 3k or 3 mths pattern right now. I usually dont bother to check the level but I did last week and it was low....08M45sport! So now I am looking at my oil a bit closer...

I would but the wife wont let me.

Would it be a good idea to run 10 30 on my 06 m45 has 138000

[Ilya]

I run 0W-40 on my current M and ran it on my old M too which I traded in a 142kmi.

[The Bodyguard]

5W30 is what the dealer uses. They used to use Castrol gtx now they use Castrol full synthetic. I use what the dealer always put in wherever I go or whenever I do it at home. 10W30 isn't much different!

[ArmedAviator]

I run 0W-40 on my current M and ran it on my old M too which I traded in a 142kmi.

This (Mobil 1 0W-40) is what I'm switching to next oil change which should be around October (7.5k miles). Probably sticking with my Fram Ultraguard filter.

Being a 0 weight oil, it is more likely to be made with a Group IV (true synthetic) base stock. It was also the only recommended oil for the GT-R....however the Mobil 1 0W-40 formula recently changed and who knows if that's still true....it is no longer list it as BMW LL-01 or whatever-the-MB-spec-is approved, but I suspect it's still just fine for these cars.

FWIW, I'm running Pennzoil Platinum 5W-30 right now and it's one of the thinner 5W-30s on the market. I think it's too thin for the occasional heavy foot driving. I'm okay with losing an immeasurable mileage efficiency with a slightly thicker oil.
