Re: What weight oil do you use?
 

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.

Re: What weight oil do you use?
 

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.

Re: What weight oil do you use?
 

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.

Re: What weight oil do you use?
 

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.

Re: What weight oil do you use?
 

Thats just plain crazy and ridiculous.

Re: What weight oil do you use?
 

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.

Re: What weight oil do you use?
 

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.

Re: What weight oil do you use?
 

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.

Re: What weight oil do you use?
 

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.

Re: What weight oil do you use?
 

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

Re: What weight oil do you use?
 

or piston slap :O

Re: What weight oil do you use?
 

I'm switching to rotella, sick of paying up the ass for mobile 1

Re: What weight oil do you use?
 

Mobil One really isn't what it used to be.

Anyone with a DSM making over 350whp should probably be running 10w40 or higher, or at least that is my opinion.

Re: What weight oil do you use?
 

True, ever since they sued Castrol (and lost) a few years ago it hasn't been a REAL 100% synthetic oil even though legally they are allowed to call it 100% synthetic.

Re: What weight oil do you use?
 

Lame, after running the thicker oil for about 800 miles, my car is now registering knock again :( wtf.

Re: What weight oil do you use?
 

It's possible you have a spun bearing.

Re: What weight oil do you use?
 

I run M1 10w-40 in my 6g76. The Mitsu book says 5w-30 but the heavier oil hushes the lifters nicely.

Re: What weight oil do you use?
 

Very unlikely (doesn't show any signs of it) but i'm clueless. I think I just have a loud engine.

Re: What weight oil do you use?
 

Has anyone used Valvoline VR1 20W50 and how do you like it? I'm thinking of running that for the summer then regular conventional in the winter.


Synthetic oil is just too expensive for me right now and is un-needed.

Re: What weight oil do you use?
 

Synth only costs more money if you insist on changing it every 3k miles.

If you take it to 10k miles with a filter change at 3500 and 7k miles, your price per mile goes way down.

But this would start the whole oil change interval argument again.
