My comment actually was refering to the point that i dont mind buying one from the dealer.But thats about it. Everything else is way overpriced.

 

wow! this is convincing. I just called Mitsu and they're telling me to buy some 5w20? Is that right? I thought it was 5w30?

Anyway, I guess it's royal purple for me now

 

I found it cheaper in the dealership than in autoparts, like a buck less...

 

The manual says 5w20 recomended but still can use 5w30. It depends on temp. 90 degrees or highter use 5w30.(According to the service manual)

 

use what is recomended

 

oh I will. Now I need to find some RP here O_o

 

that oil test just made me feel fantastic about spending 65$ for 12 quarts of royal purple...

my car will love me.
my wallets thin though.

 

Well I placed some M1 and it cost me about 43$CAD with tax for 5L and 25$ for the oil change. I think I'm going to do my own oil change next time.

I don't really feel any huge improvement but the engine seams to be a bit smoother and my gas millage got better. So it's worth it and I don't change my oil very often so it doesn't really bother me. By that I mean I don't do a lot of millage.

 

I do all my oil changes and use Amsoil 5w-30. One of the advantages of amsoil is the longer change intervals (up to 35,00 miles) between changes. I've never run it that much but the last change was done after 10k miles and the oil looked just a little brown. Nice comparo, but i noticed that Amsoil is not there, and i wonder how would it perform.

 

Just a reminder, if you're like me and don't have the time to do your own oil changes, just grab a gallon bottle of Mobile 1 synthetic from wallmart for $23. My mitsu dealer charges me $20 which includes the filter. I think i only end up paying $12 to mitsu for the labor in the end which is totally worth me not having to deal with the mess, the time and the oil disposal. I've been changing my oil every 10K miles. Its definitely worth it in my opinion.

 

I'm tempted to try Amsoil with a longer service interval. I'm tired of changing my oil every 5k miles, which is about every 2 months for me. It gets spendy. Maybe I'll try Amsoil every 10k, and just change the filter every 5k.

 

I change mine every 5K , MOBIL 1 the way to go!!! FTW!!

 

I use Mobile one on my salad..

 

I use it with girls too hehehe ....
