2Zz-Ge Oil Grade Help, Urgent

[Ash1502]

Hi, ive got a vvtli 190bhp celica tsport and am a bit confused regarding the correct oil grade.

The main dealer sold me 5w/30 fulky synthetic, and have seen other places recommend the same.

But I looked in my handbook, which says use 5w/30 for climate temps of up to aporox 10ºc, and use 10w/30 for highercclimate temps.

Help please as I dont want the wrong oil grade in my engine

I can provide the handbook picture if required

99% of people use 5w/30 in their Gen 7's, which is the general grade to use.
