which oil/grade

[nuttinfas]

got a 2005 chevy tb 4x4. We dont drive it all the time. About 10000 a year or so but alot of that is highway miles on vacation and to my parents and such. It has a slit tick when you first start it up and then it goes away once it warms up. We dont just jump in and take off we let it warm up for a few and then go. Should i run a thicker oil then 5w30 or wood 5w30 fix this if i just run synthetic or a synthetic blend? Maybe jump up to 5w20?

use what ever it calls for...weight and grade

5w-30.

 

are you sure its a engine tick and not an exhaust leak tick? the back bolt on the manifold likes to rust off on those engines so double check that.

[nuttinfas]

ill check. would it go away after about 5 secs or so?

[AJ]

doubtful but it could. its just a GM thing.

piston slap is normal on most gm's

that and if it has a plastic intake mani it might just be the valve train. Both of my camaros were/are that way.

This.

 

I dont believe those require full synthetic, they *might* require a synthetic blend if I remember correctly. But its pretty much up to you when it comes to choosing between synthetic or conventional, unless specified.
