Question

How would I know what type of oil 10 40 or 10 30 to put in my vehicle?

Answer 1

10w-30, and 10w-40 are the same low weight basically (10w) to pump easier in the cold, the end of that ( 30 or 40 ) is its weight at operating temp, 30 being a 30 weight, or 40 a 40 weight, 40 is thicker then 30 of course... you might want to try a 5w-40, a little better cold flow temp ( 5w ), and it is a 40 weight at operating temp. http://theoildrop.server101.com/ubb/ultimatebb.php

good site here for people to learn about oils.

Answer 2

It should tell you what is recommended in your owners guide. Look up oil in the index. Since you don't have the manual. I would call Toyota. They usually recommend a certain type. Using something else, although it could work can void your warranty.

Answer 3

Check your owners manual, if you've lost that you can look it up on the web. Failing all that, look on the oil fill cap it usually is listed. Putting in the wrong weight oil for your car could damage your oil pump if it's too heavy for it.

Answer 4

10-40 in the summer

10-30 in the winter



chelsea_sher..., you are wrong. The HIGHER the number the thicker the oil.

Answer 5

Either is fine, but read your manual. 10w 40 is just a bit better all around, but most cars don't need it. It is for hotter running cars. Darn, none of my nurses looked like that when I was in the hospital.

Answer 6

You Engine Requires 5W30 oil, not 1040 or 1030. Stick with what's recommended for optimum fuel mileage... Good luck

Answer 7

excuse me on my answer...my husband was not here to correct me but i do know that 10/30 and 10/40 is about the same either one is fine

Answer 8

Take it to Jiffy Lube,They have a computer for recommended oil for different vehicles.

Answer 9

winter time you use 10w40 its thinner and your engine is easier to start

summer time you use a thicker oil 30w the engine gets hotter and the heat will break down the thickness of the oil and you dont want that.

Answer 10

check owner's manual. if not there, there should be a sticker either under hood, above radiator, inside the glove box or on the driver's door where it closes.

Answer 11

It all depends on the size, age, and mileage on your car. If you have a small new car, 5w-30 is fine, if you have a big old truck, you need something thicker. take it to a repair place, they can hook it up. if you have a leak and you need to just fill it up, go to kragen and ask them there.
