Hey guys so I have finally decided I want to switch over from Mobil 1 to Amsoil. Amsoil claims you can do up 25k miles and I have seen their tests on this and show there is no sludge build up or any issues. I hope I didn't lose anyone already I don't plan to ever go that far since I beat on my car on a daily basis. I am just wondering if anyone here is doing even maybe 10,000 mile oil change intervals with Amsoil. Also what filter are you using? With the Mobil 1 my oil gets dirty by 2300-2500 miles so I change it every 3000 miles. So you Amsoil users, what's your oil change interval and what filter are you running?

 

Change it every 10-12k miles and you'll be safe. Over that you could try, but I'd change the filter and send a sample to blackstone for analysis. 25k is not realistic unless you drive in perfect environment.

 

Is 10,000 miles really okay for the engine? I know people that do like drag events or drift events and change oil right after. I drive my car hard, I hit redline at least once a day. Also I do maybe 5 drag strip runs every month too. This is the only thing that concerns me.

 

In that case is shorten it to 7k. Use a quality filter too.

 

I have narrowed it down to 3 filters I would like to use. Wix, Mobil 1, or Puralator Pure One. What do you think?

 

All are quality

 

I use their XL 5W-30 and change it every 4K or 4 months
Also use the wix oil filter.. I drive the car hard all the time..
Could I go longer probably but not going to push it I like fresh oil in the car

 

I go 5k on oil filter EA15K12, go 10k on ASL oil. I drive ~500mi a week. See their site for details.
