93 toyota pickup with a 22re w/ 190,000 miles. Im located in So Cal so temp is around 50-105 max. 50/50 freeway and around town...What weight oil should I be running???

 

What does your owner's manual say?

 

My manual says what weight oil I should use 13 years ago...Im looking for a more specific oil for my trucik 13 years later.....

 

if the 10w30 isn't feeling right, maybe move up to a 10w40 and see how it runs.

 

Ive been running 10w30 and figured I might try the 10w40 the next change. Its a little noisy but thats really my only concern. Just wondering if anyone would have recomended anything else. Thanks

 

you could also try mixing it up at your next oil change; some w40 and some w30 .personally i would just recommend that you only mix weights of the same brand to avoid any possible clash of the additive packs in different brands of oils. good luck.

 

i prefer 10w40 here in washington's climate. actually, since you're probably not going to deal much in the freezing temps down there, you might want to give 15w40 heavy duty oil a try. i like the stuff, but it's a little viscous at temps in the 20s and 30s here. not a bad summer oil up here either.

 

yup, i'm running _w40 myself here. actually, in winter (snowing now, in fact) a mix of 5w30 and 10w40. in summer a mix of 10w30 and 10w40. i've found that the rig likes the w40...

 

How does the heavier stuff affect your gas mileage and throttle response?

 

never noticed any difference in mileage when it comes to oil myself -- a slightly heavier oil will make an R series engine quieter since it's got a mechanical valvetrain.

one oil i would not recommend in these engines is any 5w30 or similar. just too thin, you think your engine is noisy now, try that stuff!
