What weight oil do you use?

So I should stop running Royal Purple and run this stuff?
Stop running RP and run anything else. There are lots of great conventional and synthetic choices available.

My favorite conventionals:
Chevron Supreme
Shell Rotella

My favorite synthetics:
Mobil 1
Castrol Syntec

They're all reasonably priced and easy to find while providing great engine protection and oil life.

I'm talkin about my talon. Are you saying I should run non-synthetic? And this oil is that good? Or are you talking about in any other regular car? I'm a little confused haha.

[Kracka]

I'm talking about any car. There is no reason to run synthetic oil in your DSM. The only reason I run Mobil 1 in my Evo is because its the factory fill. I ran Chevron Supreme in my S2000, Laser, and currently in Janelle's WRX. In some of my other DSM's I ran Rotella and Supertech (Walmart's brand).

There are plenty of good oils available so pick one and stick with it. Read that oil thread I linked to, lots of good info has been posted.

I'll read the thread but it just wouldnt feel right putting regular oil in my dsm.. I would feel guilty haha. I had to put Q horsepower in it once cause no stores were open with royal purple and I babied the car til the next oil change.

Thats just plain crazy and ridiculous.

I run Rotella 10w40 in my DSM and it works great for me. I usually throw in a bottle of Lucas oil stabilizer just for shits, and because with the external cooler, it takes 5 quarts.

I run whatever... I would feel more safe running some cheap store brand conventional oil from Holiday in any car making decent power over the water they sell as Mobile 1 nowdays.

Mobil 1 is actually testing very well in extended drain analysis. I posted Zac's analysis after 8k miles in the oil thread. Their viscosity ratings are definitely on the thin side though. If Mitsu didn't specifically recommend Mobil 1 10W-30 for the Evo I'd be temped to use 5W-40 instead.

Sweet, using some valvoline 10w-40 really helped my car run better. As scary as it is... my car no longer is registering knock using this weight oil. It really helped quiet down the engine.

Sounds like maybe you had some lifter tick that the thicker oil is helping keep quiet. Cool.
