Thanks for all the info everyone.

Well I decided after work yesterday to check a few other places, even though the deal would not be as good as walmart. (which is $30 for a 5 quart jug of Mobil 1 Extended Performance).

I checked, Walmart again, Kmart, Advances Auto, Autozone, and Target and not one of them had enough 5w30 Mobil 1 EP to do an oil change. Autozone had three single quart jugs at $10.19 a quart! So thats 3 quarts total at a rip off price out of 5 stores!

As you can imagine, I was extremely frustrated. I am definately just going to use the Mobil 1 Extended Performance 10w30 from now on. Even regular non-synthetic 10w30 is rated at as low as -4 degrees F. Synthetic however, is going to flow well much lowe r then that, so there probablly is little benefit to running 5w for m1, then 10w. I used to use thicker oils without a second thought, I just knew we had a timing chain on these that I thought was oil-pressure tensioned, but I could be wrong.

Either way, Mobil 1 EP 10w30 is available at all those places I went too, even Walmart. They have so much of it because no ones oil cap says 10w30 anymore, and no one knows any better here in NY, that they can use it instead of 5w30.

Very anoying little problem to run into every year.... but my truck will be running off of 10w30 for the rest of its life now, cause im tired of running around.

My father thinks 5w30 is too thin when cold anyway! (as do most old timers I would imagine)

 

Good deal, I know how ya feel. I used to run Kendal in my old truck just because thats what the previous owner was running and I wanted to keep it the same. Needless to say, only like 2 places carried it, sparingly at that, and it was always a pain to get.

 

So, you drove around to 5 places to save how much? What mileage are you getting? Just asking . . . .

 

You'll be fine with 5w-20, 5w-30 or 10w-30 in a 3.7/4.7. Only the engines with cylinder deactivation (MDS Hemi) do you need to stick with the one and only viscosity it calls for for proper operation.

The 4.7 HO in my '02 Jeep Overland calls for 10w-30 in the book and on the cap, I mostly stick to that but ran into a deal and half on Royal Purple a ways back (buy one get one) but was limited to 5w-20 or 5w-30. I used the 5w-30 and actually got the best fuel economy over-all during that 5k miles than at any other time I've had the Jeep. I am currently using Valvoline Synpower in 10w-30 flavor but am seriously considering 5w-30 at next change for comparison purposes...

 

It has nothing to do with saving money. Maybe you should have read my post.

I just go to walmart first, because they are by far the cheapest for the stuff.

The point of the thread was, 5w30 M1 EP is always sold out, everywhere. I wanted to see if the colder winter rating of 10w messed with the tensioners on the timing chain.

As long as I use 10w30 from now on, I will never run into this problem again, because it is always in stock, and 5w30 is always out of stock.

I drove around to 5 places to find 5w30, not to save money. No place ever has it, too many motorists around here.

 

Interesting topic, I was just going to post something about this. My 07 Dakota Owner's manual says to use 5W-20, as does the oil cap on the truck, but the official Chrysler service manual says to use 5W-30. I've never used anything other than 5W or 10W-30 in any of my vehicles (5W in the winter, 10W in the spring and summer), so I was kinda curious to see what other Dak owners used.

For reference, I've done most of my driving in Buffalo NY, then Kansas City - so a little warm during the summer, and pretty darn cold during the winter!

 

Where about's in NY are you? I only ask because my local walmart never has 10w30 but always has 5w30, how weird is that? lol
