like the title says-97' ls w/ 124,xxx miles....

i put in conventional 5w30 pennzoil but was wondering if i should use the high mileage stuff which is more expensive...what is the significant difference? thanks for helping

 

i believe there is a butt load of threads on oil already

 

Wow, a new topic that no one here has ever discussed before!

 

if you've got leaks from your motor, i would suggest the high mileage, it helps recondition the seals and fill in scuffs and minor scratches on cylinder walls to increase compression, and prevent against oil burn off. conventional is just basic, if you really care about your car, you want to use something better. how would you feel if you were your car and you only were given the absoulute basic?? consider full synthetic.

 

If you really want to protect your car, use full synthetic.

 

5w30 mobil1 full syn.

 

I wouldn't go to synthetic at this point. Stick with a quality conventional 5W-30 either standard or high-mileage formulation (which isn't much more expensive).

 

Been using castrol gtx 10-30w on my honda's for over 10 yrs. Current gs-r has over 187k miles. Call me cheap but it works for me

Synthetic is not the answer for every application. In his case, he is better off using the conventional or high mileage stuff. Synthetic is for more extreme duty and newer engines.

Does your car smoke/burn any abnormal amounts of oil? If there is no problem then just continue as you have been until things change.

 

i would prefer a mobil 1 10-30 since its a high mileage car the thikcer the oil the less it would burn

Both a 10W-30 and a 5W-30 will be essentially the same viscosity at operating temperature. Either way, trying to prevent oil consumption by using a heavier oil is generally not a good idea.

 

does not burn oil whatsover. thanks for the advice everyone-i looked through posts about oil for the difference between conventional and high mileage but couldn't find anything so that's why i started this thread...
so i'm guessing if i start to smell oil or see it burning change to 10w-30?
