Now I know Mobile 1 is recomended by the dealer but I haven't seen to much talk about royal purple, setting price aside which is better? Before I get flamed I am still new at useing the search option, damn thing isn't much help.

 

Royal Purple is probably the better oil. I use the factory fill Mobil 1 10w 30 untill I build a new engine then Ill switch to a exotic motor oil

 

I dont think there will be much difference no matter which one you use

 

Now also I hear that the Mobile filter you should use is m1-110 <--- I think that is the correct number, or m1-108. the dealer is about 1hour away so driving to get the filter is a waste of gas when auto zone is 5 min away.

 

i was recommended to use 20/50 oil for my built engine, which oil is best to use?

 

The mobil filter will work fine untill you bring it in for warranty work

Only filter I would stay away from is the regular Orange Fram. I use and also I have used the FRAM X2 on every car I have ever owned. It has about the best filtering properties on the market. Plus I get them free

 

Holy Crap 20/50...... wonder how you start it in the winter.lol

 

I hear that. Damn Mitsu. warranty

 

i run ams oil. 10w 30w. Runs smooth.

 

Yea what ever the enigine builder recomends I would use

 

It doesn't matter!!!!!!!!! Throw in synthetic and change the filter regularly and you are fine.

 

Mobil 1 is a good oil, and there isn't much advantage to switching. So I guess it just comes down to pref.

 

As long as its synthetic its not going to really matter

 

You havent heard of anyone talking about Royal Purple? Did you even bother searching.. There's a lot of Royal Purple fan boys on EvoM.. Tons of threads about oil for that matter.. Even quite a few VERY recently..

But yeah, get a good synthetic and change it at regular intervals. Unless you have a high horsepower, built motor, it's not as important.

 

Mobil one 10w30. Period!
