View Full Version : The New Mobil One 0-20w and 0-30w?

Anyone know if Mobil One has changed or they are just repackaging?

Anyway, they started to replace the silver tops on 0-20w with green and have done the same with 0-30w....wish they would offer a five quart 0-20w.

Was at a Walmart last night and really upset with the night crew. First of all, they always shut down the self service checkout so it really takes awhile. Then as I got in an express isle, an associate decided to close it then tell me to go from a five-deep line to a ten-deep line...I made sure everyone saw me drop my quart on the way out. I expected to wait, but that was ridiculous!

I was in Wal-Mart this morning and noticed they started carrying 0W-20 again. I have been purchasing Amsoil inline which is a bit of a hassle.

Hi Chuck:

___All I can say is Halleluiah and I am not too concerned with the switch from gray to green caps myself ;) Has the price gone up much that you saw last night?

___Good Luck

The price seemed to be the same as previously. I think the new color cap is for marketing purposes.

Changed the oil yesterday, was going to go with the Mobile One 0W-20 or even 30, but I couldn't beat the deal on the jug of 5W-30 - a good $5-6 cheaper than buying 4 quarts of the others. I know I'll have a hard time recouping that $5-6 in FE dollars.

Oh, and this was at Advanced auto... approx. $6.50/quart, approx. $22/ 4 quart jug.

-edit-
I'm not even going to touch it up... my math is way off. Woo hoo US education system!

I paid $5.97 per quart.

Comparing the new with the old cans (0w-20):

old one: ACEA A1/B1----------ILSAC GF-4----API SM, SL/CF
new one: ACEA A1/B1-04----ILSAC GF-4----API SM, SL/CF

I've been running 5W20 all winter, versus the recommended 5W30. Now that we are going into the warmer weather, should I switch back to 5W30, or will the 5W20 be adequate at 55 MPH or less?

kwj - 5W20 is probably fine for the summer.

I've bought M1 0W20 at WallyWorld for the Insight last October... silver cap back then...

Wild guess: the 0w number is the more critical number on hybrids because of the frequent restarts. In the winter it's even more important....0w-30 is probably better than 5w-20, but I'm guessing.

Hi Chuck:

___30W would be bad for an Insight’s FE and just about anything else that can use lighter weight oil (about everything nowadays). The first number is a measure of a drop test through oil at 0 degrees C and the second is at 100 degrees C. Kinematic viscosity is the result IIRC and the lower that number on each end of the spectrum, the better for FE.

___Good Luck

Are you talking about the new "Mobil 1 fuel economy" oils rated at 0W - 30? Saw it for $21.97 / 5 qt. I'm gonna give it a try next time!

If your car specifies the use of a 5W-30, then you should probably stick to that or 0W-30. The 30 is used to indicate the viscosity at the normal operating condition of your engine. The clearances of the bearings, rings, oil pump, etc, are designed for this viscosity. If you run a thinner oil than recommended, it can decrease the lifespan of the motor.

The first viscosity number indicates the cold motor viscosity. Even a 0W is usually not thin enough to give the designed oil flow and proper viscosity to the engine when the motor is cold. So a 0W is usually desirable. 0W-20 for engines recommending a XW-20 and 0W-30 for those recommending an XW-30.

I saw 0W30 mobil1 in 5qt jugs in Wal-Mart last night. I plan to switch both my ranger and my Z28 over to it. Ive been running 5W30 mobil1 in both vehicles for years.

Great. I have yet to see the 5qt. jugs of 0W M1, so I'll cross my fingers for the next time I need to change the oil.

I've always ran 5w30 M1 in my truck..

I saw the 0w30 and went for it... 21 something before tax..

It was actually a buck or two cheaper than the usual 5w30 I usually get..
marketing with that green cap got me good! ;)

I just put M1 5w20 in mine. It calls for 5W30. I had conventional lube-shop 5w30 in there before this.

It's odd that this thread got bumped as I was just buying Mobil1 synthetic motor oil 2 days ago. I was trying to get the 5W-20 EP again. My Yaris came with 5W-30 from the factory and that's what's listed in the owner's manual but Toyota released a TSB last year advocating 5W-20 for all *NZ* engines.

Anyway, my usual auto parts store - Kragen - had no 5W-20 EP, nor even a SKU for it. They called 2 other shops in town and they had none, either. They sent me to Pep Boys. Pep Boys had only 1 quart of the stuff. They sent me to NAPA. NAPA had none of the EP formulations at all.

Out of frustration I stopped by Wal-Mart on the way back home. They had no 5 quart containers but they had enough quarts to cover me. So I just made my first Wal-Mart purchase in more than 6 months, and I am not happy about it. :(

how will running 0w30 effect a vehicle spec'd for 5w30 in reguards to cold climate?

I can't quite remember the numbers of what stands for what..

Hi Brian:

___I spoke with a Prius heavy member yesterday and he said the TSB was for all NZ engines but the Prius? Can you find the TSB online so I can verify? If I owned a Prius, I would be running 0W-20 in that too given the TBN’s from analysis are so perfect but for those that want to be within every spec, I am just wondering is all?

___Chris, the 0W spec is a measure of kinematic viscosity at 0 degrees C or cold and Mobil10W is about the best you are going to get w/ a pour point down to almost 60 degrees F below 0!

___Good Luck

Was in WalMart recently and they had 5-quart containers of 0-30w Mobil One. They never have had 0-20w that size, but I'd grab it in an instant.

Wayne,

I've uploaded the TSB to our Files section: http://www.cleanmpg.com/forums/downloads.php?do=file&id=31

It mentions no exclusion for the Prius (1NZ-FXE) and I can locate no newer TSB that would supersede this one..

This is a quote from the posted TSB. For Prius vehicles, refer to TSB No. EG050–04, “Engine Oil Specifications.”

TSB EG050-04 says to use 5w30.

http://stuff.jaygroh.com/prius/Prius%20Info/Official%20Toyota%20Info/Repair%20Information/Service%20Bulletins/Engine%20Oil%20Specifications.pdf

With that said I have been using 0w20 for the past two oil changes and have had no problems. The oil analysis for those two have been very good.

Hi Jay:

___That was close. I was in the process of PM'ing the TSB info when you posted yours.

___I have swapped out the Prius' I have driven for any lengthy distance with 0W-20 each and every time too!

___Good luck and thank you!
