Mobile 1 5w50
I just read about mobil 1 5w50 was factory fill for lexus lfa. I didn't even know they made a 5w50.
Anyone have thoughts? May be a good option based on being between 0w40 and tws |

I've been thinking the exact same thing having recently changed to 0w40. I live in a relatively warm climate (40deg C) in summer and wouldn'tmind a halfway house as I don't want to change the oil based on season especially as I only do about 5-7000km a year... would love to hear people's thoughts/comments...

It's spelled MOBIL. There is no E on the end.
Anyway, the 5w50 is pretty boring. Their 0w40 is the halo product and is far better on paper and in practical use. I don't really put much faith in what a blender parades around as "factory fill for X"...that stuff generally comes down to economics and negotiation. Why do you think BMW switched from Castrol to Shell/Pennzoil? MONEY.

Just get a jug of M1 15W50 at Walmart and mix it in with 0W40. There's even a rebate right now.

Been running a mobil1 0w40 and 5w50 blend for the summer. Gets to temp fast, hardly burns any, and seems very stout under hard driving in the insane socal summer heat
I picked up a bunch of the 5w50 when it was on sale at NAPA for $7/qt. A few months ago |

I'm looking for data or experience but not sure you saying it's boring adds data What's boring? I also think lfa is different as toyota doesn't spec mobil products in other cars so it was interesting. Not much data. I don't care about cost. Just pure health of engine |

The datasheet just doesn't impress me compared to the 0w40. Mediocre VI, just a few/older certifications (which indicates an older formula), poor MRV. It has a nice starting TBN, that's about all. For the same money, or even less, you could have the 0w40 which is a fantastic oil. As far as Toyota not using Mobil products in their other cars, that doesn't mean much. Mobil may have simply cut them a smoking deal just so they could advertise "our oil is in the Lexus LF-A". Last I checked, the Toyota-branded oil was blended by ConocoPhilips but that does tend to change every few years when they negotiate a new contract. Would the 5w50 work in the S65? Probably. Can you do better? Definitely.

There are guys on here who have tracked the car with M1 0w40 and their UOAs have come back just fine.

Oh cool, didn't know they switched suppliers. Maybe it was Honda that used CP. I don't remember now. LF-A is a high-revving V10, yes.

I just switched to Motul 5w40 a few hundred miles ago from 10w60 castrol. Got to say im liking it much better, smoother revs engine is also more quite on start ups. Of course it gets to temp much faster and seems to bleed heat much faster as well which is very nice.

What? M1 5W50 is a racing spec oil, while 0W40 is silver color coded, middle tier oil. Even their M1 Advanced 5W30 is stronger than it, with a golden color code, and 15,000 mile guarantee to stay in grade.

You tried this rhetoric in the track section of this forum, and was laughed at.

What's this M1 Advanced 5W30 you are talking about? Got a link to the product?
There's no way M1 5W30 is stronger than M1 0W40 for performance application, judging by certifications and the data Exxon/Mobil publishes themselves. |

I use the "halo product" term on the 0w40 simply due to it's outstanding specifications and the vast list of certs it carries. IIRC it was the first of their oils to use the new proprietary Visom basestocks. I'll admit that I use the halo term loosely, and that it may not necessarily line up with XOM's marketing department. I try to look past the marketing whenever possible. I'm simply not a fan of the 5w50. Older specs, older certs. It's not a "bad" product, it's just that you can do much better for the same money. I welcome your perspective.

certified RACING spec oils, cannot be compared to street oils in terms of performance.

But M1 EP 5w30 is irrelevant in this discussion. It's not even remotely close to the appropriate oil for this engine. Again, it all comes down to picking the right tool/equipment for the job. M1 EP 5w30 and M1 0w40 are not similar products, plain and simple. BTW, M1 0w40 is a race oil and is actually a spec oil used in several race series. It's factory fill for all Porsche spec racing cars, for example (Mobil and Porsche openly advertise this). When I was watching the 24 Hours of LeMans last year I caught pit footage from Porsche and saw them pouring it in. It is also factory fill on several supercars like the GT-R, which we know are targeted at weekend racers. Have you spent any time reading up on this stuff on Bob Is The Oil Guy? There are a lot of tribologists that frequent the site and tons of hard data around oil blending/formulation, certifications, and so on. There are even employees of XOM, Castrol, SOPUS, and other supermajors that routinely share their years of experience. Pennzoil has had big Q&A sessions with members. There's a lot more to an oil than what the marketing department prints on the bottle, though sometimes you can really gleam some good info from the technical data sheets and MSDS online...or by asking! I've routinely asked a lot of hard questions to these companies and gotten back detailed answers.

I never said M1 0w40 is remotely close to TWS, but it is certainly closer than M1 EP 5w30. If you believe so strongly in the EP 5w30, feel free to run it. It is your car, after all, and your decision. I'd never use it in the S65 -- way too thin (HTHS under 3.0). I'm also a bit confused why you keep calling it Mobil 1 "Racing" 5w50. There is an actual Mobil 1 Racing 0w50, which they don't advise for street use.
Like anything else, I encourage OP to go do the necessary research and make an informed decision. Reading marketing lingo on Mobil's website isn't going to cut it. I'm done arguing about this. Now I remember why I don't come on this site much anymore (or any online forums, for that matter).
