Oil Type

I know my TS should be running on 5w 30 oil but i am due a service so i'm going to get some fresh oil, in this case it will be Comma fully synthetic. (cus i can get it cheap)

Anyone use fully synth in their yaris? or is semi synth ok for it?

Any other makes preferable to comma?

I do plenty of miles so dont really want to go putting normal garage crap in it!

you can use the following for the TS

cold climate 5W/30

moderate climate 10W/30 or 5W/40

hot climate 20W/50

What oil weight is the Comma oil you want to use?

I use Castrol RS 0W-40 (full synthetic) in the Yaris, I can get it at a good price and never had any problem with their products.

The 5W-30 that is being stated for most modern engines has actually more to do with manufacturers being able to meet emission regulations better more than anything else.

I use Mobile1 and it get the job done... a bit expensive though...

yvan, it will be 10w 40 it is very popular on a vast range of modern cars in this country, will this be detrimental to a VVT-i?

i've used it in my VW's and also in a few Zetecs but not sure on the VVT-I getting bunged up!

No problem there, as usual when cold give the engine time to come to temperature before giving it some.

oh, and when you change oil also use a new filter, some oils don't like being intermixed very much, better safe than sorry.

I use the Castrol fully synth 10-40W... the expensive stuff with claimed power gains etc... it's pretty good!

I change the oil every 4000 miles just because the car gets some serious stick, and it's definitely made a difference in acceleration... I tested similar stuff in some bikes, back to back on a dyno, and the difference was like 5bhp more per 100!
