Mobile 1 0w-30

[clemsonfor]

What are your thoughts on using in it. I use Mobile 1 5w-30 in my toyota and have since we got it 30,000 miles ago. This is a 2001 model Highlander 3.0L v-6 motor.

The packaging on the 0w oil says for all vehicles requiring 5w-30 oils. I understand what the two numbers mean and the 0 is the cold viscosity at some temperature. And that when warm or hot it performs as 30w oil in both of these products cases. My question is what is 0w , water? Should i worry about this in my toyota. I was thinking about it for winter use and know it should be fine. But i do only live in SC were not talking supercold temps here. What about summer performance when its 95F out?

I was reading the lable and the fuel savings chart is what peaked my interest and got me to thinking about using it.

I am sure it would be fine, but why change what is working for you? Mobil 1 5w30 is excellent oil and provides all the low temp performance you need just about anywhere in the country, especially in SC.

Storm why change, the advertised fuel savings. But as K7 points out it may only be a few percent under ideal conditions "ignoring gravity" as my college physics teacher always said. It just claimed something like $450/yr savings.

I use the M1 0w-10 in both my Toyota's (Tacoma & 4Runner) but it gets a little colder up here in PA. Down in SC...6 in 1 and half a dozen in another.

Or did it say something like "up to" $450/yr? That should always be read as "less than". FYI - I have some swampland in Florida for sale.

id have to look again. It was a chart with multiple columns, i think it may have had to do with # of miles driven like 10K 5K etc assuming fuel at $2.50/gallon. But like you point out this is probably Alaska like conditions on 40 below zero days so the 5w is really thick. Here even when i did the oil changes in like 40F weather the 5w seemed like pretty thin oil to me, nothing that was going to cause that much drag in.

I switched my previous vehicle, a 2004 Chevy s10 PU with a V6 ofter to 0-W30 and picked up 1 MPG. Not really worth doing it on MPG savings alone.

That last comment in what I quoted tells me that you DONT understand what it means. I don't mean to come across harsh but it is the truth.

If you are already using mobil 1 5w30 synthetic, 0w30 is in every way better. It is NOT like water. Oil DOES NOT get thinner when you run it.

All it means is that it flows like a 0w oil would when cold and like a 30w when heated. But when heated, it is STILL thinner than when cold. The reason that it is better is because it flows better when cold, getting to vital points in the engine quicker for lubrication. I dont buy into the better mileage hype. Because when it is warmed up, it has the viscosity of a 30w just like the 5w30 you are running. So it you heat them to 100 degrees and up, there is absolutly NO difference in the viscosity. But at colder temps, it is thinner than the 5w30, but even then, it is still thicker than when you reach operating temps. That is the big misconception on multi-viscosity oils. It does NOT get thicker when heated. It still gets thinner, just NOT as much thinner as a straigh weight oil.

I hope I cleared some things up. And I apologize if I sounded mean, because I don't mean to be. But you have everything to gain by switching and nothing to lose.

Edit: And if you are already running the fully synthetic 5w30, then there would be no cost increase as they are usually the same price. $20-$21 for a 5qt jug at Wal-mart.

I would have a real tough time believing that you could realize any savings. I used to have a Northstar V-8 Cadillac. I was using Mobil 1 5w30 and switched to Rotella 15w40. I saw NO difference in fuel mileage and I as a rule check every tank just because I am kind of **** about such things and also because it is a good way to catch if something is starting to go south. So I remain a doubting Thomas that you would see any difference in mileage. But hey, go for it and let us know!

But i am already using Mobile 1, just not the 0w-30. It costs the same thing as what im using so if i could pick up 1 mpg it would be worth the swap as there is no cost difference.

Thats a good explination. I did not explain myself well enough, i just gave a real quick blurb and yea it could be read like i dont understand. I totally understand what your saying. 100F 30w, 10w-30 and 0w30 will all be the same viscosity cause there all 30W when hot. Cold is a different story. The 30w is like honey and the 10w30 just thick like that choclolate milk you buy in the store and 0w30 is really thin. And yes i know a 5w30 is thicker that even hot 30w. My real question is that 5w 30 seems really thin even at 35F, what has the viscosity of 0w? Viscosity is the ability to flow and i beleive it is through some known diameter hole and in this case were talking cold flow rate so its at some degree (that i really dont know, not sure if were talking 0F or 20F), what is another liquid with 0 viscosity.

My point is there is a huge diffeerence to me in 10w-30 and 5w30. Shaking the 0w30 bottle its not that much different sounding to me??
