Is 15W-50 M1 EP too thick to use?

Your statement fits into the category where not only do you not get it and are in the wrong, but you are also haughty and insulting.

Do oils really work like that?

There are viscosity calculators that you plug in some required info, found on spec sheets and it will give you the viscosities of the end product.

Here's one: I think there are others too.

Why thank you.

+1 it is on clearance for a reason.


+2 What are you saving?! 10 bucks a year? 20 bucks? even 30 bucks a year won't be worth causing wear in your engine. Most oil is relatively the same price even when it is on sale. The money you save is such a small amount. Unless you buy a boat load of oil at one time that happens to be on clearance.

This is not my thread but I bought the same clearance oil as the OP and above I have posted a lot of analysis including what I'm mixing to get my desired 100 C viscosity, how many quarts of 5W-20 to buy, and the cost per quart of my oil blend.

You questioned how much money is saved. For me it is ~$60. To someone like me who doesn't have money to throw away, $60 is a good savings and I'm getting an oil mixture that I am confident will work very well in the vehicles it will go in.

"Causing wear" in whoever's engine is not a foregone conclusion.

It's not really about saving. It may actually be that 15W-50 provides better protection for warm weather, highway driving.

Honda recommends thicker viscosities for its engines outside of North America. I don't get the impression that the 5W-20 recommendation is optimized for minimal wear under all conditions. Perhaps 15W-50 might even do better under these conditions?

I agree. Especially if you do a lot of highway miles with lots of miles at full temperature and fewer warmup cycles. That's why I went with the straight 30. You figure 15-20 minutes warmup, 4 hours straight on the freeway and that was it. One warmup cycle for each 280 miles driven.

My car`s owner`s manual and FSM (my 3000GT`s said the same thing as my Z`s) to use 10W30 for fuel econony and 10W40,15W40,15W50,20W40,and 20W50 for racing and extended high speed driving, It then says not to use 5W30 except in extremely cold conditions (for the n/a motor) and not to use it in the turbo model whatsoever.

It is perfectly fine to buy the right oil or an oil that will satisfy your engine especially if you are in an extreme climate. It just sounded as if people were buying any 'ol oil just because it was on sale. Sorry for the confusion.

Either way, I'm all for thick oil. But some applications do not benefit from it.

By the way, I do not have the "Thin" oil mentality that most North Americans do. I prefer the thick stuff.
