Mobil 1 question?
Hi There:
I was wondering why Mobil 1 fully synthetic 10w-30 does not say that it meets the GM 4718m spec. Only meets the GM 6094m. The 5w-30 f/synthetic meets both specs. gm4718m,gm 6094m . I just checked this today, looking at the 5 qt. container. I wanted the 10w-30 weight but bought the 5w-30

Strange...this page says https://www.mobiloil.com/USA-English..._1_10W-30.aspx
Mobil 1 10W-30 exceeds warranty requirements for gasoline engines where an API certified oil is specified. It meets:
ILSAC GF-4 (API Certified - Starburst)
API SM/SL
GM 6094M/GM4718M
Requirements for Diesel Powered Vehicles where an API CF or API CD is Recommended
ACEA A1/A5, B1/B5
Mobil 1 10W-30 is recommended for all types of modern vehicles, including high-performance turbo-charged, supercharged gasoline and multi-valve fuel injected engines found in passenger cars, SUVs, light vans and trucks.
Mobil 1 10W-30 is general purpose engine oil for all types of vehicles where a 10W-30 viscosity is recommended.
Mobil 1 is not recommended for 2-cycle or aviation engines, unless specifically approved by the manufacturer.
For more information, see the Mobil 1 10W-30 Product Data Sheet and the Material Safety Data Sheet.

Hi There:
Thanks for the link. I read that.But thats not whats on the label. 4718m for the 10w-30 is not there,but 6094m is. You,re right strange. I was in Walmart this morning $22 for 5qt. container.

I know I'm going to get flamed for this, but if you've never used anything other than Mobile1, give either German Castrol 0w30 or Amsoil 0w30 (the oil I use) a try. You'll be pleasantly surprised how quite the valve train will be and how much smoother the car will feel.
Just my 2 cents...
Oh, Amsoil is truly the best oil there is. It's used in race cars, but it does cost a bit more than others (at 9.xx / qt).

I run 5W-30 all year, even in the summer. I live in Phoenix where we just had the hottest July on record....and I still use 5W-30. Stick with it and you'll be fine.

This is no longer an issue when it comes to modern synthetics though. A 5w30 conventional oil will thin out a lot quicker than a 10w30 conventional, but when it comes to synthetics that doesn't happen.
In the oil analysis reports I've gotten with Pennzoil Platinum 5w30, the final viscosity ends up being 11 cst at 100c after 7000 miles, exactly the same viscosity the oil starts out as when new. So it's not thinning out whatsoever. IMO, 10w30 synthetic is obsolete, as 5w30 can do everything it can do, with the added benefit of flowing better when cold.

I've used Mobil 1 synthetic but switched to Castrol synthetic on my last oil change, 5w-30.
Both oils I'm sure work very well. I asked my mechanic why he switched brands. He said something I thought was very interesting and on the surface made sense, but I really don't know if it is true or not. He said that each manufacturers oil contain different chemical properties ; that by swiching oils ypu will have the benefit of a wider spectrum of chemical properties and that was better for an engine than just being exposed to a few chemical properties in one oil. This kinda made sense to me but I don't know if it has merit.

Hi Rob, Maybe due to the hurricane Katrina, and the disruption of Mobil facilities down there that you got a 5 qt container with a misprint ? Wouldn't be the first time I've seen that happen ! Hope everything works out OK for you. I used to use the Mobil 1 10w/30 and at Corvettes at Carlisle one year I got talking to a Mobil engineer and he convinced me that using 5w/30 was much better due to where I live, (Cold winters) and since then I just always buy the 5w/30 at Wallys place. Usually cost me $29.97 for 7 quarts. Good luck buddy !
So stick with 5W-30, 0W-30 or even 0W-40 synthetics and forget about old school 10W-30.

I did the same a few years ago when I called Mobil. Rgw tech guy to whom I spoke told me that 10W-30 synthetics are essentially obsolete. That viscosity oil cannot "pump up" as quickly as a 5W-30 during startup, even when the temp is 70 degrees F.
So stick with 5W-30, 0W-30 or even 0W-40 synthetics and forget about old school 10W-30.

Do these (either 30 or 40) work for our vettes? Anyone tried them? They are new to the market but it seems promising.
