How many "thick oil users" here?

[Olas]

10w40 all year round - my owners manual says it is good from minus 22c to positive 35c.

I've never seen it so cold or so hot in this country and is are better now than they were in the 80s so I don't need to give it any more thought...

That's one way to get that oil pressure light to go out!

A few days ago I switched from 15w30 to 5w30 when I saw temperatures in the teens in the forecast.
I started my car at 21F earlier this morning.

I'm sure the 15w30 would've been fine in this weather, and I probably shouldn't have even bothered.

Using 0w30 myself. Does that put me in the thin oil crowd?

HTHS over 3.5cP though, does that put me in the thick oil crowd?

 

[simple_gifts]

Using 0w-40; Will be moving to 5w-50 (thanks AZ) next spring.

I (my car) has a bit of a consumption issue.

Count me out.

I have 0W30 in my Tundra's sump, and today had me rethinking that. At least for winter months. Oil pressure gauge stayed stuck well above normal on a quick drive; and after a good 10 minutes of driving 50+mph, I accelerated up a hill, at 3k. Pressure was at 3/4 (of whatever, as Toyota thinks owners are morons who don't need numbers). Makes me want to run 0W20 in winter, xW30 in summer. I do think it ran a bit more quiet on 10W30, last summer; and it calls for 0W20 year 'round.

10w30 in most of my vehicles. I'm in

Edge 0w-40 in my F150 Ecoboost, but I'm sure it dilutes / shears down pretty quickly, so no real danger to the engine.

I have to ask just because. What would be the danger running the 0W-40?

 

[TiredTrucker]

Yep, 10w30 in most of what I run. From a little Yamaha EF2000 generator and JD Zero turn mower, thru my 2006 Cadillac and 2015 Silverado 2500 pickup, right on up to my 2013 Freightliner semi truck which currently is pulling a 53' dry box trailer with 23 tons of bulk bag popcorn in it.

Point was made and is valid.... 10w30 is not any "thicker" than the OP 5w30. Same viscosity at operating temp.

I'm running 10w40 in my 03 Crown Vic. I also live in So. Calif. She rattles for the 1st second or two if it's in the 40's or colder but other then that the car runs great.

I remember growing up we had a 89 Mazda B2200 pickup that always got PYB 20w50 and a small bottle of STP oil treatment. Never had a problem.

 

[jongies3]

Unless it's an old engine I see no point. 5w30 in my truck although I'm considering using Pennzoil Ultra in 0W-40 because it's one of two PU grades we started carrying at work and since PU is so hard to find this may be my only way to run it.

20W-50 User here, does that get me into the thick oil club?.

 

[901Memphis]

This runs fine in the winter, but only after I start a fire under the oil pan

 

[Revving2Redline]

I'm in recovery as I used 10w30 in Everything to even include my Hyunda Accent that was GDi with PUP 10w30.Now its on to the 0w20 gravy train.

 

[slybunda]

[censored] designed engines need thicker oil. That seems to be the general concensus around here.

 

[FCD]

20W-50 seems to be the boogeyman of Bitog.
All i can say my engine purrs on it, because it was specified for it when new, i would never use it in something that specs a 30 grade oil.

Good chart. I think what we need is an official BITOG (non)scientific test, get someone to start their vehicle at a very cold temp with 0wxx in the sump, then again in the same conditions with 10wxx in the sump. Parked overnight in low temps, video the whole thing and post it up for us to watch and fight over.

The worse I ever see in my area is in the -20F range. That is "maybe" a couple days a year. Most times, temps never below -10F all winter, and not for extended periods. majority of temps 0F or higher. All of these lows are generally night time temps. And in my case, my personal vehicles all sit inside garage at night. 10w30 has never been an issue for me. What someone has to deal with makes the choice for them. If I ever move back to the interior of Alaska, I will rethink what I am using.
