Just wanted to see what everyone thought about Mobil 1 10W30 synthetic oil. I have a 2003 GLE that is about to get its first oil change so I was thinking of running that.

 

There are tons of threads on this, some on the first few pages. Search is down but scroll back and you'll find some.

Cliff notes:

- Mobil 1 is a great synthetic, some prefer Amsoil but it is more $$.

- It's best to wait 6-10k before switching to synthetic.

 

It's actually alot less money than Mobil 1 according to the oil analysis spreadsheet

 

Just wondering,
why wait until 6-10K for the synthetic? Something to do with the seals?

P.S. Do synthetics use a special oil filter?

 

Why wait till 6-10K for synthetic??? Some org. members say that the 3.5VQ isn't fully broken-in till around 6-10K.

 

Yeah but then you get into the whole extended drain interval thing right. I know some people run Amsoil up to 20k between changes, making it cheaper than the 3 or so Mobil 1 changes you would do in the same amount of miles. Personally, I'd rather use Mobil 1 on a 5k change schedule and not have to worry about having problems with my warranty. Just my opinion.


You can use any filter, but you want to use a good one. Mobil 1 makes a good filter for the 3.5, the M1-110. It's around $12. Another good one is the K&N which is around $10. Some people stick with the OEM Nissan ones which you can get for around $4 each.

 

the new SRT-4's come with Mobil 1 synthetic stock and require that oil only, nothing else..

I switched at 8k

 

Hey, i heard that mobil 1 synthetic oil is not a true synthetic oil?!?! its a mineral based synthetic, is anyone else aware of this?

Amsoil is a true synthetic oil.

Does everyone know this?

 

Mobil Tri-Syn was mieral based, but the SuperSyn is in the same category as the Amsoil now. There is no doubt that Amsoil is the best. It's been proven time and again with oil analysis and wear tests. That being said, most people don't drive their cars 250,000 miles and Mobil 1 SuperSyn can most certainly get you to that level. I personally use Amsoil just because I'm a freak and want the best, but I also change it in my Max every 5k. I change it in my Durango 2 times a year.

 

It's all in the brew...

If I understand it correctly, Mobil 1 is made by "refining or ameliorating" oil(as a chemist i can get into the semantics of it but...they can actually control the type and length of hydrocabons they want to make)... ie. Mobil 1 petrochemical-folk actually know whats in the quart, better hydrocarbons that are "made" or "synthesize," which can withstand high temps and impede (not prevents)oxidation for a longer period of time, when compared to conventional motor oil, which is a smore-gaas-borg of stuff.

Amsoil is porbably synthesized through a similar process OR these magical petrochemical-folk actually "build up" their hydrocarbons.

Bottom line:
A)stick with conventional and OEM filters @~3000 miles

B)stick with synthetics (Mobil or Castrol) and OEM filters @~4000 miles

C) B good quality filter

IMO unless you track your car from sun up to sun down OR drive home on the NJ turnpike and your Max is S/C, you really shouldn't spend to mcuh $$$ on oil...Mobil 1 is good enough...We're not driving twin turbo GT-R Skylines fellas or Murcielagos...Our cars are fast, not rockets...
