What SYNTHETIC oil is best? One of the best I know that isn’t too expensive is AMSOIL. I don’t know where it’s sold in canada but they’ve got lots of dealers that sell it in the states. One that’s widely available but is definately better than most other brand names is Mobil 1. ---

My mechanic uses Kendall GT1 High Performance synth-blend. I know Kendall has been around for a long time, but I haven’t heard anything about how it stacks up against Mobil, Amsoil, or Motul (shows how much I trust my mechanic! 😛 ). ---

I only used regular Castrol GTX (in following weights): 10w30 - Summer 5w30 - Winter No problems (yet). Right now I still have 5w30 from the last time I changed in Nov. 03, so for the summer I will be switching to Amsoil synthetic 10w30. ---

Mobil 1 is the best oil out there, it dosent burn as fast and is the only full syntetic oli out there, only thing is its like 30-40 a bottole (the big one) and once you use syntetic, never go back to the regular shit, my friend messed up all his seals that way and everything so its eaither stay with the good stuff or never goo there from what I know most JDM use syntetic ---

Hah, I work at CT and we don’t have AMSOIL oil in our store… yet. ^^^ I don’t see how you can mess up your seals by using synthetic and then back to regular oil. ---

holy shit 25,000 MILES between oil changes … im gonna grab me some of this sh\*\*… is this stuff real? my normal synthetic needs changing every 5000km if this is true this synthetic would actually be cheeper than others because you wouldnt have to change oil every few months.

I gotta call BS on that. No matter how good an oil is, it will still get contaminated over time. It says it’s good “up to” 25k miles. “Up to” can mean a lot things to me. It’s like saying brake pads for “cars” at CT start at $12. But since you’re driving a 240, they cost you $54.99. [Next page](https://forums.speedlife.net/t/what-oil-is-best/80701.md?page=2)
