Motor grease - what does 10W50 or 10W40 tight-fisted?

what is the difference? My husband accidentally bought 10W40 instead of 10W50, can he still use it?

It depends of the vehicle, age and driving conditions, I am
not an expert, but it's the category! one is heavier than the other
and I will suggest to check the owner's manual for the
right title of oil required for you vehicle, sometimes it
matter to the life of the engine. You can hail as the auto parts
place and ask them by giving the make and year of vehicle
also the mileage on it as all right, they will recommend.

There is no difference between 10W-30 and 10W-40 grease. However when the engine is hot, the 10W-40 oil is thicker than the 10W-30.

This is why single-grade oil are very unpromising. Straight 30 weight grease is way too gluey when cold to properly lubricate the engine.

The only process to use single weight grease is to have an grease pan electric fire to bring the oil up to operating warmth (about 140^F or 60^C) before the engine is ever started. If you simply must use it, this type of grease should only be used contained by race engines beside pan heaters.

Answers:    these #s are viscosity ratings , the lower the # the lower the temperature it will pour at for the first one , the W scheme its winter rating , the second # is for how high a heat it can handle minus thinning out . if you get frost you should coppers it to a 5W/30 , hope this helps .

Still not start up. what wrong beside...


Depends on what kind of sports car, and where you live. The 10w-30 is a thicker grease than the 5w-30. If you're in a radiator climate(like where it's not below freezing) next it shouldn't make much of a difference. The grease will take a moment or two longer to warm up to the fluid-point to be a angelic lubricant for your engine. If you live in the northern areas- I wouldn't use it, I'd embezzle it back and grasp the right stuff. The most important rationale is because in a cold start your engine is relying on the grease to become fluid enough to lubricate, and the heavier grease makes the engine run longer in need being properly lubed. That's why it's also a upright idea to consent to the engine run a few minutes before driving contained by the winter- to get the grease warmed up so it can do its work and you'll have a great deal fewer problems down the road
