Did the same thing back and forth myself and everyone has their opinion.

When your car comes with a Mobil 1 sticker (or used to, you can still see the little rectangle on the engine cover if you look close), that is good enough for me to stick with.

 

I have a hard time seeing it being safe for a 4g63 and unsafe for a 4b11

 

After all my research, the only thing that really seemed to matter was changing the oil regularly.

 

Maybe..but a simple "evo x best oil" or anything along those lines, google search bringing up as many threads as it does shows how **** we are, and for good reason.

 

I use Mobile 1 5w-30 + K&N HP-1010 filter for every oil change. I'm at 90k miles, daily driven. Zero issues, even with a stage 2 tune.

 

I used valvoline syn power on my previous evo that was making 460hp and never had any issues, so ima do the same for my new evo

 

I been using Mobil 1 from walmart full synthetic 5w-30 for like $20 but the jug says "Dexos1" right next to the 5w-30... anyone heard of this? I been running that for about 2.5k miles with no problems..

 

I saw tht one at walmart also. There were so many thats why i wasnt sure the Mobil 1 0w40 for european cars was the right one or not. I will try rotella t6 since its so readily available.

 

ive heard nothing but good things about rotella t6. also amsoil, im sure theres a store near you that carries it. I live in iowa which is full of nothing but corn and theres a store 15 min from my house that carries it.

 

I agree, read the label do what it says, But i use mobil 1 5w-20. No matter what you decide on, changing it on a regular basis is key. 3000k miles is what i do for all my cars.

 

I did my first oil change at 500miles with Mobil 1 EP, second at 1000miles with mobil 1 EP, and i will be doing my third at 3k miles with Rotella, then every 3k miles after that with Rotella.

 

so does anyone know if this Mobil 1 "dexos1" crap will mess up my car?

 

I would highly doubt it. Dexos1 was just a new oil standard that GM created for newer engines. I doubt that Mobil 1 drastically changed when they adopted the dexos 1 spec. I use Rotella T6 myself now (but ran M1 for the first almost 100k miles in my evo). I wouldn't hesitate to use it.

 

From years of running various turbo cars heres what i think. Pick a synthetic oil and stick with it. Theyre all about the same but regular changes are a must. Changing brands back and forth can lead to trouble as the different additives can interact badly over time.
Conventional oil is good for engine break in as it will help with the initial swelling of gaskets and lets everything seat properly but it will also coke in a turbo car. This coking will build up and clog oil lines. Switching to synthetic at the first change will flush out any small amount of coking present.
People will argue that brand x is better than brand y and what not. The bottom line is that you should stick with your personal preference and change it regularly.

 

Same here. Used to run it in my BMW track day cars
