ive heard its not really worth it to change to synthetic oil after a certain amount of miles. is this true? i have 123k just about 124. is it worth it to go synthetic? which brand? full or blended?

 

With that many miles I think your engine has grown too accustomed to standard oil to swith at this point... I could be wrong tho..

 

since you haven't used synthetic motor oil i wouldn't use it. my car has 126,000 miles on it and i use the higher mileage motor oil and some duralube when i do an oil change. i've heard when your engine gets over 100,000 miles synthetic motor oil is not good for your car because your engine will tend to have oil leaks. it's not my opinion just what i've heard.

 

Shoot Im over a 121,000 miles and Im using sytheic motor oil and I dont have any leaks. I started using it around 112,000 or so. Dont remember when I started to use it.

 

i agree with forty. changeover should be between 75 and 100 thousand.

 

i'd go with a "high mileage" synthetic. something that will help recondition the seals & stuff.

 

ya...thats what the high mileage oil is all about, its soppsed to seap into seals and make them less prone to leaking

 

where can i get this high milage synthetic??? never heard of it. ive seen like all the regular high milage stuff but never in syn form

 

the one i know of is made by kendall. it's called GT-1 HIGH MILEAGE WITH SEALMAX.

 

I switched to syntetic in my old Audi 100 and it had 250K on it. No leaks, no problems. I switched it on my civic when I bouth it with 110,000 on it. I say go for it. I personaly have had no problems with doing that. I think if your car already leaks oil though, then I wouldent.

If you goto mobil1's website, there is a section where it explains the myths and whatnot about switching at high milage.
