For same price, Choose Mobil 1 EP over Mobil 1?

[BigNick]

Background: Car is a 2008 Chrysler 300 3.5L V6, bought new, Mobil 1 10W30 since 5,000km, now with 16,000km, doing 10,000km OCI (ok with warranty). Probably drive 10,000km in about 9-10 months, mostly normal city driving, 6 quarts per oil change.

With Advance Auto's new sale (5 quarts any Mobil 1 product with Mobil 1 filter for $29.99) wanted to stock up on some Mobile 1. (I'll be using the Mobil 1 rebate with the 5 quart Walmart Jugs in April) I think it's a great deal with the filter included.

My question is, since you can get ANY Mobil 1 product with the sale, including Extended Performance, Should I just get 6 quarts of the EP over the regular Mobil 1?

Extended Performance specs, closely match regular Mobil 1, but supposedly has more additives and "stuff", that allow for the longer OCI. So for the same price, wouldn't it be logical to basically just get the same product with more "stuff" in it!? I question this for my application, but also in general...

Would regular Mobil 1 be BETTER in my application than using Mobil 1 EP? If yes, why? ....

Lastly, since it takes 6 quarts, Maybe a mix of the products would be "better"??? eg. 4 quarts Mobil 1 10w30 + 2 quarts Mobil 1 EP 10w30?

Mobil 1 EP is just going to retain it's Tbn a bit longer than the regular M1, although I've yet to see it really work as claimed.

BigNick,

If it basically cost the same then I'd go for it. That way you can always be sure you have extra additives until the next OCI.

Sure, why not? The EP should have higher TBN.

If the vehicle is covered by an extended warranty, I would not use EP since Mobil 1 EP is not warranty approved.

There would be no way they could prove(simple UOA) what oil is in the pan.

A normal new-car warranty would theoretically require the manufacturer to prove the lubricant to be the problem (though that's a whole other story in reality), however, an extended warranty is considered to be a service contract and the owner is obligated to follow the warranty company's requirements.

I agree^^^

I guess I don't see how this would be an issue with a new car so long as the owner didn't take it out past 0% on the OLM. EP is API SM and GF-4 certified. In GM vehicles the main thing is the 6094M spec. This oil does meet 6094M in the weights for GM line-up. What's the issue?

You're right, I'm wrong. I didn't realize that Mobil 1 EP now contains the "donut." I always thought that Mobil 1 EP did not carry the same certifications as the regular Mobil 1. I guess the formulation had changed and I didn't know that.

Just cleaned out my Advanced Auto of their supply of EP-5w30 and M101 filters. I am going to change this oil out only when my OLM tells me too. Awesome deal at 29.95 for extended performance.

Not too long after they launched M1EP, the GF-4/SM specs showed up on the bottle. The tweak was made years ago.

The "donut" and "energy conserving" designation (at least for 5w30 and a few others) only showed up within last few years (not sure when). Prior to that, the Mobil 1 website mentioned that EP did not meet warranty specs for new cars, but that is no longer the case.

I picked up 10 quarts of the M1 EP 5w30 and two M1-206 filters on Saturday. I'd have gotten more but at this point I'm at a two year supply of the stuff. Prior to this I'd been running regular M1 5w30, but I still plan on changing per the OLM.

Here's a question: I've got two quarts of M1 5w30 left over in a 5 quart jug, and 10 quarts of M1 EP 5w30. Does anyone see the harm in mixing them together (my car takes 4 quarts) for my next oil change? I'd like to use up my remaining 5 quart jug.

No harm at all go for it..
