Mobil 0w30

[dougkmcse]

Any one checked it out? I just saw it at walmart. Is it as good as Castrol 0w30. That is what i use now with no oil loss between oil changes after 55k.
Thanks

UOA FTW!

Mobil1 0W30 is geared more towards fuel economy. It's thinner than GC at operating temp, has a lower High Temp High Shear and meets Energy Conserving requirements.

A big difference is GC gets the ACEA A3 spec.

Syntec PDS .
M1 0W30 PDS .

Castrol SYNTEC 0W–30 European Formula is engineered to meet the Mercedes Benz 229.5 specification. The 0W–30 viscosity grade is ideal for winter conditions where low temperature pumpability is required. A unique, low–temperature formulation provides exceptional pumpability in cold weather and allows for unaided engine starts down to –40ºF. Exceeds all car and light truck manufacturer's warranty requirements for the protection of gasoline, diesel and turbocharged engines where API SL, SJ, SH, CF or CD is recommended. Exceeds European ACEA: A3, B3, B4; VW 502 00, 505 00, 503 01; MB 229.1, 229.3, 229.5; BMW LL–01; GM–LLA–025, GM–LL–B–025 and the engine protection requirements of ILSAC GF–3 for API Certified Gasoline Engine Oils.

Mobil 1 0W-30 meets key builder specifications:
GM 6094M, GM 4718M (Corvette spec)
Ford WSS-M2C929-A
ILSAC GF-4
API SM/CF
ACEA A1/B1
Mobil 1 0W-30 is an advance performance synthetic engine oil designed to provide cleaning power, wear protection and enhanced fuel economy performance. Mobil 1 0W-30 offers an enhanced fuel economy formula and exceeds the requirements of the latest industry standards required by newer modern gasoline and diesel powered automobile engines.

Mobil1 0W40 has pretty much the same European auto maker approvals as Castrol 0W30. The low HTHS of Mobil1 0W30 scares most Euro makes from recommending and meeting approval.

I think i will stick with the castrol
Thanks for the info....

I think theres a big hipe around Mobil1. I would use whatever is cheapest. I've had great success with Castrol in reducing oil consumption and easy start up, but that was with my Volkswagen.

cheapest... that is pretty much the reason so many people run mobil1. next to the walmart synthetic, mobil1 is the cheapest name brand full synth oil.

The Rotella-T 5w-40 full synthetic is cheaper than Mobil1 and has been working well in my Legacy for the past couple of oil changes. The only "problem" is that it only comes in 4 quart jugs, and I need almost 5 quarts for an oil change.

I like it because the motor makes less noise when hot than with the Mobil1 5w-30 I was using before. Other people's UOAs say it's good.

I wouldn't count rotella since that is marketed as a diesel engine oil. Farm equipment with a gas engine is their only gas engine application.

Nice post, bluesubie, good info. I bought a bunch of it to run in my dad's Sienna minivan as he is always running around all over the county, and logs his mileage. He has been using regular Mobil DC 5w-30 with short OCI's as it is one of the listed Sludge Monsters. Got it specifically for the 2% mileage claim, and it is the same cost as the other weights of M1 at ChinaMart.

In speaking with the M1 engineers and tech geeks at SEMA last year, they said it would likely replace their other weights (doubtful), and they were Nerding it up talking about it. The Marketing guys barely knew what it was, but the engineers and chemists that were there were happy to discuss....that was October 2007, now it's out ~6 months later. We'll see. If it's okay, then we'll run it in the wife's Accord V6, if nothing else for the *potential* for increased mileage.

cst @ 100-deg C = 11.0 , not "too thin" by anyone's book, but I will likely stick to my 40-wt oils in the Subaru. Kind of low TBN at 8.5, and low-ish HTHS number compared to even other weights of M1. Minimum 800ppm of Phosphorous. Wonder what the fuss is about, without seeing a VOA?

the guys at bitog seem to like it a lot, anyway its designed for diesel applications but still suitable for gas engines

Yup - it can clog your cats if you burn oil, but the only oil I've ever used is when an oil filter seal started weeping because it was defective. Other than that, all good.
