View Full Version : M1 0w-20 Vs M1 5w-20. Gains?

I know the 0-20 Mobil 1 has lower kinematic Visc and all, but how much real world MPG gain are users seeing with this oil??? The 0-20 costs much more than regualr M1 5-20. And you can extrapelate that to Dino 5-20 which is a 1/2 of regular M1. The point of MPG savings is $/Mi savings.

Not for everyone, it isn't. For many the point is the reduction in tons of emissions. That can be harder to put a price on.
You are sure it costs more?
I am pretty sure they are the same price at walmart.

At Kragen, they are the same price.

I saw no noticable difference between mileage from 0w-20 to 5w-20 mobil 1. My oil change interval was 7500 miles. Mobil 1 5w-20 was used before and after the 0w-20. It's cheaper for me to buy the 5w-20 so that's what's I've been using; plus its not very cold here.

No noticeable mileage gain on 0W-20 compared to M1 5W-20. Car clattered something awful as soon as I switched. Never again.

For some reason my local wal-marts don't have a shelf sticker for 0w-20. It's like they have a limited about of 5qt jugs of M1. Eitherway, I've been doing more reading up and theres no MPG difference, FL never gets below 50*F... so theres really no point for going against honda's recommendation of 5w-20. Looks like it's either Pennzoil platinum vs M1. OR if I go cheap Yellow bottle Pennzoil vs Mobil clean 5,000. For me the reason I bought this car, and the reason I try to max MPG's is $/mile.... just an opinion. :Banane28: dude the bananas on this site are cool as heck. :Banane18:

The 0W-20 is labeled as "Mobil1 Advanced Fuel Economy" and usually is limited to quarts.

All of the different things that I've seen about fuel economy rate using lower viscosity oil as being worth a 1-3% improvement. Going from 5W-20 to 0W-20 probably won't give you a FE improvement of more than 1% unless you use your car a lot in cold temperatures, which in Florida you definitely won't be. However there are advantages of choosing synthetic oil and that's something to think about.

10-4 guys. I did some more HW on my oil options. Pennzoil Platinum 5-20 Synthetic is about 3% thinner than Mobil 1 5-20. It's also $2/5qts cheaper. From what I've read it's not as good of a full syn as M1, base stocks etc. But I'm not racing my car, not towing, no turbo... and It's a newer, low mileage well maintenanced Honda. So I think my next oil change will be with PP 5-20. Give them each, M1 & PP, a run and see how they each do (currently running M1 5-20). Thanks guys.
___What is the Penzoil 5W-20s Kinematic viscosity at 0 and 100 degrees C as that is the key comparison for improved FE.
___0W-20 is the best we have right now and there is a difference but you will not see it except maybe .2 mpg over a tank vs. 5W-20 Mobil 1.

My civic calls for 5w30 and the Ody calls for 5w20. I'm using M1 5w20 for both, so I only have to stock one thing in my garage.

Found that Yellow Bottle Pennzoil 5-20 is another good, cheap option for the Dino 5-20 class. VERY VERY low Kinematic Viscocities. Even lower than M1 5-20. Thus far I've been very very happy with M1 5-20, as I should be for the price tag! lol. So as far as MPG's is concerned only in real cold weather I'll a Synthetic show real improvements, correct? (especially for a 5-20 that's so thin already). Next change will be Pennzoil Plat 5-20, then Pennzoil Yellow Bottle 5-20. That way I've run all 3 contendors and can go from there. See if one burns off quicker, or if any. or any other observations like cold starting etc. but I think any of those 3 oils will treat MPG's well. I am a bit weary of the 0w-20 b/c of the reports on here and other forums of some cold start rattle noises.
___Your Accord is perfectly happy with 0W-20 if that helps...

Just a note, my dealership should but does not supply 0w20 motor oil, unless ordered from a auto supplyer. The pruis 3 requires 0w20. We have only done i think one oil change on the prius 3 since they came out. So im thinking that if you need a oil change make sure they have it if you want 0w20 oil.
Another thought i have is that because 0w20 is not in bulk (at least at my dealership or for that matter any other motor oil thats not in bulk), that means that the oil comes in containers. To me I wonder how much oil it took to make the containers and to transport it to the dealers. And once used the containers go in the trash and end up in a landfill, adding to the plastic mess we already have. I bet that it takes way more energy and resources to make, package and transport these containers then its worth. So to me, im thinking that unless there is a significant increase in FE with 0w20 compared to 5w20, is it really worth it? Im not sure if it cast more, but unless someday when I buy a hybrid (used probably) it absolutely has to have 0w20 I really dont think im going to use it.

echoman- I change my own oil, at home in my own garage. Never had anyone else oil in my cars before. I do it all at home. So I usually pick up my oil in 5qt jugs from wal-mart while we're there already for other items... which lately hasn't been much. I haven't been to fond if wally world pushing advertisment for Obama-Care. Not to mention they only have minimal registers open so you always have at least a 20min+ wait in line and you can't think the the place.

In practice, I strongly doubt you'd be able to detect the difference between 0W and 5W oils.
Very well said. I still seem to think that the 0W20 oil must have an adventage, but if there is no noticable difference then whats the point?
echo for you there very well maybe a point to it.
0w is a bit better in Cold Start up Conditions.
