AutoZone Mobil 1 5qts oil & filter special $19.99

[Brabus]

Wanted to let everybody know that AutoZone has an incredible deal on Mobil 1 oil and oil filters.

You get 5 quarts of Mobil 1 synthetic oil and Mobil 1 oil filter (whether jug or individual quarts) for $29.99 (That's normally $34.99 plus $12.99 for filter). If you want the Extended Performance (the change every 15,000 miles kind) plus filter is $34.99.

That and Mobil 1 has a $10 rebate on 5 quarts of oil, limit of two rebates per household, so that's how you get $19.99. Even $29.99 for 5 quarts and filter without the rebate is good. The sale ends August 26, 2009 at AutoZone and I believe the Mobil 1 rebate ends shortly thereafter.

So here's the deal. I have two households, so I plan to get 20 quarts of Mobil 1 oil and four filters.

My question is the type of Mobil 1 synthetic oil. I've read through the forum and there's a lot of talk about oil types. My decision is for either:

5W-30 Mobil 1 Synthetic (which is GF-4 certified)
5W-30 Mobil 1 Extended Performance Synthetic (GF-4 certified)
0W-40 Mobil 1 Synthetic (NOT GL-4 certified)
5W-40 Mobil 1 Synthetic Turbo Diesel Truck (CJ-4 certified)

Now normally I wouldn't consider something that says diesel, but in a thread on here someone said we should consider it, so I'm putting it there as an option. So before I spend a bunch of money getting 20 quarts, I'm wondering which one people would recommend.

Is the EP (extended performance) better oil? Like I realize it's suppose to last 15,000 miles versus 10,000, but wondering if it's better even if you decided to change the EP oil every 10k miles. It's a buck more per quart.

darn...
and I just did my first oil change today.. pep boys was $27.00 for the 4 quart jug... $7.00 each for individual quarts...

wish I had gone to autozone .. oh well

First of all, analyze your driving situation. Does it constitute “severe service” or “normal (ideal) service?” Google that if need be. Many more people than they think are actually in the severe category for one reason or another. If your usage is severe, the oil change interval should be shortened between 1/3 and 1/2 of the normal/ideal interval, and Extended Performance will then do you no good. The smart regimen for normal driving is 10,000 miles or 1-year, whichever comes first - nowhere does anything say that 15,000 miles is recommendable.

Then analyze your operating climate to choose an appropriate viscosity. Guidance is now included in the ’09 OpMan. The reason that smartUSA uses 0W-40 everywhere is that they now supply the dealers with Mobil 1 oil as a smart part out of the Tulsa depot, and a single brand and viscosity is simple and cost effective for them.

This IS a great deal.....too bad I just changed mine about 1,000 miles ago. But you can bet I'll be checking out Autozone FIRST! I did buy my 0W40 Mobil 1 there but I used the OE filter. I'm planning on using the Mobil 1 filter AFTER I'm out of warranty.......it's only one more change at 20K.

As to your question, from what I understand, it depends a lot what kind of climate you have. If you live in the northern part us the U.S. (like CT), you would use 0W40 as I do here in Indiana. If you live in southern CA or FL, then maybe a 5W40 would be best.

What... didn't you use Amsoil?????

I looked at the recomendations in the book.. and for here in South Louisiana I went with the 5w40 Mobile one..
and like you, I think I will stick with mobile one and the filter from the dealer until the warranty is up...

The oil change place I use for my wife's car uses castrol sysnthetics if you ask for synthetic.. but they just charged me $72 for a synthetic oil change@!!!! ouch...
THe smart is so easy.. I quess I am back to changing my own oil again.

So if I'm a severe driver then I should change the oil every 5,000 miles rather than 10,000?

In terms of severe driving, I'd say about 1/5th of the time I'm in the severe driving category. Rarely do I sit in congested traffic, certainly don't drive in dusty conditions, in typical redlight city traffic, occasional sustained highway traffic in hot weather (i.e. our hot weather doesn't last long and sub-zero temps last a bit longer), not a big idler, so dunno if I'm severe, but I don't mind changing it sooner.

So if I'm suppose to use 0W-40 since I'm in CT, then I guess my question was about this certification. The CF-4, CL-4, CJ-4...the 0W-40 doesn't have any of these, but I guess this isn't important.

I suppose I should buy Smart filters. Sigh...BTW, my dealer wants $96 for an oil change.

...1/5 of the stuff that makes severe driving is NOT severe driving...
...0-40...and the filter of your choice...I run the Purolator.....just me...

You may want to consider Mobil 1 Advanced Fuel Economy 0W30 Fully Synthetic motor oil.

Don't confuse the API commercial/diesel service classifications (e.g. CL-4, CJ-4, etc.) with the ILSAC GF-4 standard for gasoline engines. ILSAC GF-4 is a strict international performance standard that only some API, ACEA and JASO grades can make. One of GF-4's characteristics is that it conserves about 2% of energy. No oil with a winter rating above 10W or a normal rating above 30-weight will be GF-4. API uses a starburst symbol on the packaging of API classified oils that are also GF-4.

Oddly enough, since 2004 M-B's exaulted Sheet 229.5 of required/recommended oils says they must be a "minimum 1.8% fuel saving," and yet there are a number of non-fuel saving (non-GF-4) oils listed.

My local Auto zone is 2.5 hours away. Looks like I will be looking for a sale elsewhere.
