Synthetic Oils

Re: sythetic oils

Sythetic oil is superior to conventional oil, but because most of us have a car worth less than $6000......
 


Re: sythetic oils

I switched from conventional to full synthetic at the 218k mile mark.Im on 258k now and i dont notice a performance difference, but i dont notice negative effects either.No smoke, doesnt get babyd either.I run royal purp or penzoil ultra.
 


Re: sythetic oils

decided that since 0w 30 royal purple does so good in the bike that i would try it in my wifes cobalt. it is the 2.2 non turbo and its brand new. instead of 0w 30 i went with 5w 30 just because the car doesnt rev that high. with normal full synthetic from castrol the car is averaging 29 mpg with my heavy ass foot. this includes city and highway driving. we bought this car in august and it already has 17k miles on it. i have made 2 trips from missouri to atlanta in it. both trips i averaged 36 mpg.

we will continue to use the balt the exact same way as before and i will update you guys on whether it did anything for fuel mileage or butt dyno.
 


Re: sythetic oils

There is a NAPA store about an hour from me that sells it by the quart in bottles. I always buy a 30 gallon drum, though, and the Schaeffer guy delivers it to my house.
 
Re: sythetic oils

I have used castrol syntec, mobil 1 and royal purple. I used to get what ever was on sale. Now I have switched back to mobil 1 and will stick with it from now on.
 


Re: sythetic oils

i use mobil 1 10w30 for oil and amsoil trans fluid in both my gp's. Only oil filters i buy say acdelco or mobil 1 on them.
 
Re: sythetic oils

I read a thing on a forum a few months back that even ACDelco was having some product quality control issues. So my faith in them has pretty much deteriorated.

I've always used them because I get them cheap....but oh well.
