Well Im due for a new oil change and I just want to know if Castrol Syntec oil is the way to go.
I know synthetic oil is much more thin then just regular oil and that it last for more then 3K miles, but does it have that much of a diff. over the regular stuff?
and
I also was told that once you go synthetic with your oil, your motor is required to have synthetic for the rest of its life? Is that true?


For about $5 a quart, this oil better live up to its price!

 

Castrol GTX! :thumbup: I actually had been using Mobile 1 Synthetic but switched back to conventional oil with no problems.

 

I use the Syntec blend in my girlfriend's car. She had been burning a good amount of oil before and it fixed that right away.

 

The viscosity of synthetic oil is the same as convetional oil. 5w30 is still 5w30.

 

I run Castrol GTX, with changes every 5000 miles or 6 months. In combination with Hastings™ Oil Filters, I have had very low oil consumption. It'll need about 1/3 qt of oil between changes.
I heartily recommend both products.

 

i run syntec blend... something like taht.... i like it
