Its summer time in ohio and i want to know what grade oil to use, gimme a clue here. 160k on engine. check the owners manual, perhaps ?? I'd imagine 10w30 would be safe enough, no ??

Even 5w30 would probably be fine, but yeah, 10w30 should be good.

In the summer in a older 160k engine?
10W30

Im using 10w40 in mine, 180k is that fine?

Preference. What numbers sound best to you? In the manual it should say 10w 30, stick around that.

You should always stick with a 30w type oil. If you switch to a 40w, it takes your oil pump a lot longer to get the oil up to your cams during start up.

When you look at the numbers for a blended oil ie: 10W30, the 30 stands for the viscosity at about 100 degrees celcius or 212 F, near most operation temperatures, and the 10 tells you about the curve of the viscosity versus temperature.

All the critical clearances in your engine are designed to have a 30w type oil flowing through them at all times. IF you use a thicker oil, you run the risk of the oil not flowing efficiently to your parts, and also the oil will produce more heat, as a result of the parts having to overcome the thicker oil film/greater film strength.

If you have are having problems with burning oil, a thicker oil is not going to help that. Time to replace your valve seals or rings. ( I would guess valve seals in a celica)

The first number just says how well the oil will flow at low temp, and how well it will hold its viscosity at high temp. Basically, a 5W30 is designed to be THINNER at LOW temperatures, and THICKER at HIGH temperatures than a 10W30, so all round, it is a better oil. That being said, more engineering goes into it, and that is why it costs more than a 10W30.

That is enough of an oil rant for now...

I use 10w30 in the summer, and 5w30 in the winter.

My Jetta uses 0w40 all year...

Back when I had my Sentra, though, I used 5w30 in winter and 10w30 in summer...

0W 40?
Is it a diesel?

Say what?

10 is the viscosity at 0*F.
W means winter grade, basically works with the 10.
30 is the viscosity at 212*F.

A 5W30 is designed to be thinner at low temps [5W=winter grade], but the SAME viscosity as a 10W30 at operating temps.
And they cost the same.
At least everywhere I've been.
I can't speak for you Canadians.

I see it's a 2.0T, so diesel, right?

I might be wrong but i think 0 is imported oil ya im serious lol. I think its a standard in europe sort of. Expensive junk.

It's not imported oil.
You can get 0W20 0W30 0W40 at pretty much any auto parts store.....
Common for European cars, and some new Toyotas can run it as well [0W 20]

It's just oil that has the same viscosity as 0 weight oil at 0*F.
No more expensive either.
It's just like 5W30, or 10W 40, or 20W 40, or whatever.
Just different weights of oil....

Did you read what I posted?

I use 10w30 in the summer, and 5w30 in the winter.
same here in my 93 st

To clarify, my original surprise was not the 0W, it was the 40.
Most newer cars run 20 or 30.
Older truck engines [like mine] and diesels run thicker oils like 40.
My truck runs 10W40 in the summer and 5W40 in the winter.

Nope, it's a 2.0 Direct Injection gasoline turbo. The VAG diesel is a 1.9T. I'm not sure why they have such a wide viscosity spread, probably to try and get oil to the turbo as quickly as possible while it's cold (peak boost arrives at less than 2000 rpm so it's hard to stay out when the engine's cold)...don't know why they go as high as 40, though...
