Stick with the standard type 10w30 for the time being bud.

Once you know more about why you are changing things, then you can start mucking about with them. ;)

It dont matter.

i run 20-50 alot of the time in any car with higher than 150k.

Correct weight is over rated.

No, correct weight is not at all over rated.

You made an informed decision to use the specific weight you are using because you know the vehicle condition and history.
Temperature and climate also have an effect on this, as is shown in the service manual.

For someone that does not know about their car, they need to stick to the basics.
This includes using the OE recommended fluids.

Please explain WHY you are using the oil WEIGHT you are using in your car.

This is not to be a discussion of brands.

If we are going to help people understand the WHAT to use, we should provide the WHY.

10w30 because I can get it cheap in the motormaster brand, Rotetta-T in 5w30 is almost twice as much money.

according to the oners manual you can use 5W-30 IN THE WINTER. but usually 10w-30 is fine year round. it has to do with how the oil reacts to cold/hot temps. i used to know ther official reason,it in one of my books somewhere)s i use 5w-30 in the winter time and 10w-30 in the spring and summer months

well when i worked at the GM dealership i learned that the oil your car is rated for how fine of holes and gaps it has to get into therefore the thicker the gaps between things the thicker the oil it can take, the closer the parts are together the thinner oil you should use. which makes sense cuz if you have a fine gap between any moving part common sense would say that finer oil would lubricate that better than thicker oil due to the fact that it can access that area quicker...

Izzy....

Please post in a readable fashion.
You do not at all use punctuation and it makes things incredibly difficult to read.

I use the sandy kinda oil.... with diamond grits.





5w30 now that the oil leaks are gone, used to be 10w30.

oh, and the w doesn't stand for weight.

Viscosity rating: 5 WARM 30.

Are you sure W doesn't stand for weight?...... :rollseyes:

Come on now.

W does not stand for weight or warm, it stands for winter. The first number followed by the W is the oil's viscosity rating at 0* F. The second number is the oil's resistance to thinning, and also is viscosity rating at 212* F.

dont celicas take 5w-30?
You can't lump together all versions of a car that has been around for forty years and had more then ten different motors. Some Celicas took 5w-30 from the factory, not all. Tell us year and sub-model or we can't give an informed opinion.

Thanks Cannon. Apparently my sarcasm was lost.

I use only the finest fresh squeezed oil from atlantic sperm whales.
Or mobile 1 5w-30, whichever one walmart is stocking at the moment.

I use M1 0w-30 in the Tercel, but I am trying to squeeze every little bit out of that engine without modifying it, and it's a cheap engine, so i'm not so worried.

Absolutly no problems after two years though.
