on my gmc truck i run 10 30 penzoil but it has 252xxx miles, now what can i consider to put in the camaro 116xxx? ive been giving it alot of thought but what can y'all guys recommend?

 

Synthetic, name your favorite poison. Some people think that synthetic costs more to use. But when you figure it has twice the life of conventional oil, and you're changing the filter half as often, it ends up costing you less money and time in the long run.

 

thanks synthetic it is!!! and ill go with your personal favorite mobil 1,

 

Conventional oil can sludge up inside the engine. Synthetic oil has anti-sludging properties, and can actually start to clean away sludge that you might have. If your engine has only been on a conventional oil diet, you would want to keep an eye on the dipstick and see how well the oil is staying clean. You may want to do your next oil change a little sooner, depending on how it looks. I generally go 6-7k miles between oil changes. You have to change your way of thinking when using synthetic.

 

yeah because i have no record on the camaro and im scared it wasn't very loved lately before the guy sold it . oil looks bad. i'll just keep an eye on it as you said then from then ill wait 4-5k before changing it if it does not look bad after the second change ill, change it every 5-6k at the most.

 

I was using Pennzoil ultra with mobil1 extended filter. for about 2yrs. I switched back to dino oil and fram filter. supertech 5w30 and a toughguard filter changed every 3k now.


I think my car runs quieter/smoother with conventional but could just be the lack of sleep iv been getting.

 

what weight should you recommend i go with?

 

5W-30 or 5W-40 is more than good enough.

 

thanks ill go with 5w-30

 

One of the most important questions to ask, is the motor a roller cam or flat tappet. With the lower amount of zinc starting back in 07 it will make a big difference to the motor running a 5w30 with a flat tappet cam.
