Either
Higher quality base stocks have lower pour points
Or
You can tell the quality of an oil by its pour point.

Multi-grades are better than mono-grades in hot weather.

We spend 99% of the oil change process on discussing and debating, which will make no more than 1% of difference as far as engine life goes.

True story.

I stopped talking to people, including at Walmart but yeah, I gave a couple of free classes right there in the oil aisle a time or two.

Mostly to people with a 40 - weight oil in hand, of some kind.

I did this just a couple months ago. I went into walmart to use the 12 dollar rebate thing. A guy was there going back and forth between the castrol and and valvoline high mileage oils. I grabbed two jugs of mobile 1 high mileage and he said that he really liked mobile one but wished they made a synthetic blend high mileage.

I responded, "ah ha! But they do!" And showed him on the back of the jug where it said synthetic blend and told him of the online rebate. He immediately grabbed the 10w40 and I asked him what vehicle. He said it was an 01 chevy with the 5.3. He told me the owner's manual said 5w30 but his uncle told him 40wt protects better. Also, he wanted synthetic blend because changing every 3k miles was expensive with synthetic.

We talked for another 5 min or so but he wound up getting the 5w30 mobile super high mileage and a fram ultra. I only told him the common sense stuff I've learned on here. I hope he went to at least 5k on that oci.

Edit: no I didn't tell him mobil super was better than those. Mobile was the brand he preferred.

No, your just repeating the light weight engine oil BITOG mantra.

I agree with the 10W40 being the better choice instead of 5W30 in Alabama especially in a 14 year old vehicle.

I hope his uncle made him take the oil back and get the 10W40 instead.

 

[Justin251]

I sure doubt you believe a 40wt is always better. Especially for a passenger car or truck that sees little sever duty or towing.

I disagree with it being perfect for alabama. 20wt and 30wt are fine here. It's not that dang hot.

 

[Garak]

Out of curiosity, is your Mobil Super HM ILSAC rated or not? I know M1 HM is not, but our Canadian Mobil Super HM is.

 

[Justin251]

I'd have to go to the website and see. The guy wanted a mobil branded synthetic blend high mileage oil and that's it.

I think it's weird that mobil doesn't put that on the front of the bottle.

Edit: yes it is. Except for the 10w40 version.

 

[Garak]

Thanks, was just curious and theorizing that Mobil Super HM in your neck of the woods is the same as up here. We certainly don't get actual M1 HM up here, though.

"It that dang hot in Alabama."
Another myth busted.

OK, so its not hot enough to warrant a 40, but cold enough to make 5W30 a better choice than 10W30, 15W30 or SAE 30?

Do you need a multi-grade XW30 in Alabama, or is that another myth busted?

Run Forrest.

If you use any weight other than that stated in the owner manual, your car will lock up. 5w20 with flow at -50 below and 10w30 comes in a tube like tooth paste.

I didn't say any of that. He told me the owner's manual called for 5w30 but his uncle said 10w40 protects better. Which going by the info on here is an incorrect general statement. Which is what I told him. Some vehicles is does some it doesn't.

He made the choice to go with 5w30 because its not wrong. 10w40 could be better in that engine neither I, he, nor his uncle know that.

We have gm 4.3 v6s in our fork trucks at work and they all get rotella T 15w40. That same engine in my old Sonoma called for 5w30. They don't have engine problems in those trucks.

So no I'm not a subscriber to the thinner is better always. But we beat the [censored] out of those fork trucks so maybe the 40wt hdeo has something to do with them running so well.

Thanks for the regional slander at the end there.

Edit: before it's mentioned I got the m1 ep 0w20 for my truck for $1 a quart. Otherwise I'd never but it and just run a 5w20 or 5w30. As long as the mds works I'm happy.

The fact that Wal*Marts in Montgomery have 0W20 is a marketing success story.

I agree. Really. But hey good for me 0w20 and 0w30 is the first on clearance! Ha

Have you ever tried to pour a 5w-XX at -30 C? At that temperature, yes, a 10w-30 would be perfectly at home alongside toothpaste. I had to top up my LTD many years ago with 5w-30 in sub -30 C weather. I foolishly had the oil in the trunk and did actually have to squeeze the bottle like a toothpaste tube!

Back in the day in Saskatchewan they used 10W in the truck and a campfire under the tractor.

Garak, my big mistake yesterday was turning south off #1 at Maple Creek, around the Dollard loop to Assiniboia then east on the "Red Coat Trail". The "oil money" doesn't start until Weyburn. Some short cut that turned out to be. Tell Brad, less complaining and more paving.
