Costco has never carried 15w50 synthetic before and I am currently running Rotella 5w40 with moderate usage.

Now that it is going to be warmer, what say all of you about puting this in my 1993 with 207k on the ticker?

Too thick?

Also saw it in there, but the price was not much of a discount - near $5.50 a quart or something still. Wasn't enough to pull me from the Rotella Syn.

I don't know how much Wallmart sells it for. But they sell it in one gallon containers which I like. I fill the empty oil containers with used oil to take down to the recycling center.

That's they only product that makes me go to Wallmart...

Agreed, walmart is a PITA.

Oil and shotgun shells for the sporting clays. Cheap by the case there.

I do the same thing with the gallon jugs BTW, works great. However, I always have to have the quarts on hand for toppers.

Since you have to buy more than a case (6 pack) to fill the LC, buy one case of 15w-50 and one of the 5w-30 and blend them (4 quarts each) when you fill the LC. It will give you approximately a 10w-40 oil.

I wish Mobil 1 kept their old formula for 15w50 (red cap version). I used to use it in all of my cars and motorcycles. Since the change I can't use it in my motorcycle anymore...

Don't you guys find the 15W/50 to be a bit heavy for our trucks?

Doesn't that put a much greater pressure on the head gasket and internal workings?

I'm all for using a heavy oil living in San Antonio with our blistering summers but I've got to shake that bad ju ju feeling of heavy oil.

I've always thought a 10w/40 would be about right but I'm open to opinions. I know the "recommended" weight is 5 or 10/30.

Thoughts?

Toyota recommendation for the rest of the world is 20W-50 for hot climates, so that's what I run in my rig. Toyota recommends 10W-30 for ones operated in the US, so nether is wrong, run what you feel comfortable with. It's been beat to death search some oil threads.
