I resently because a distributor for Amsoil products and I was looking through the oils and they have a synthetic that lasts for 25,000 miles!! Has anyone used this at all and is it any good? I run Mobil 1 full synthetic in my 07' Si and if this stuff is any good I was thinking about using it since I get it for Whole sale...

Thanks

 

i have been using motul full syntethic in my honda and i can probably recomend this oil Amsoil as far as i know is good but just for gearboxes

 

I also use Motul only but Amsoil is very good also! I much prefer it to Mobil 1 any day of the week...

 

Ok. I'll just stick to Mobil 1 then. Glory United DaveSi677!!

 

I run Amsoil synchromesh transmission fluid. Mobil 1 motor oil. No problems here.

 

i've been running amsoil full synthetic 5w30 for about 5k miles and it looks just like the day i put it in. unfortunately i blew the motor recently so it's probably contaminated with metal bits now. lulz

 

Haha glad to see another United fan here!

 

From what I've read, Mobil1 5w-30 is just so-so; I ran that for a majority of the life of my FA5 and also Valvoline Synpower 5w-30 for a while as well (prior to reading up on Mobil1).

I haven't used Amsoil but did use Royal Purple for a bit. It was way too pricy. I recommend Mobil1 0w-40 as it is very good and reasonably priced - supposedly it's almost like a race oil. Look it up on bobistheoilguy.com.

 

Yea the Mobil 1 5w-30 isn't that great. Check out bob the oil guy.

I have used amsoil 5w30 signature series synthetic on my turbo fa5 and it has been great (3k interval changes though). Will probably be switching to rotella t6 5w40 diesel oil :giggle: for future changes since its supposed to be really good as well and is significantly cheaper than the amsoil signature series and since I am not intending to take advantage of the long change intervals I think I can save myself a little money by using the rotella.

 

My car ran with Royal Purple when it was brand new till about 60k. I switched to mobil 1 because of cost. But I have recently become a distributor for Amsoil so I get it for $7 bucks a quart which is about what Mobil 1 is going for around here. So I figured I'd see if it was any better.

 

Amsoil is very good.. I rate it higher then Mobil1

 

$7/quart is a really good price. I've always paid around $10.

 

I pay $10 for Royal Purple. That's expensive for Mobil 1!!

 

Sorry if my post was confusing. I meant I usually pay about $10/quart for amsoil signature series synthetic.

 

i keep saying Motul FTW!

 

Royal Purple is $22 a QT here that's why I use M1 but would rather be using RP anyday.

 

22$ a qt that is crazy!

I pay 35$ for a 5L of Motul...
