Ive heard SO many dsmers say rotella is great. Would it be a good oil for me to run? Brand new engine, acl coated bearings, break in has been done. All mods in profile up to date.
The only concern i have is its really thick oil. They dont sell rotella 10/40 at this walmart, thats what id prefer.
 
i run rotella 15-40 in everything I own. I started running it in the talon after 5000 break in and have never had a problem. Diesal oil is high in detergents so its better to run in it new rebuilt engines to prevent sludge buildup. Id recomend running that oil.
 
The Rotella T6 synthetic is the one you want, T5 is the contenvional oil. If you can find 10W40 that would be a little better than 15W40 but still good to use. I'm running T6 5W40 in my VR-4 and will be in my Eclipse.
 
Agreed, I wish they had a 10W30.
 
Use Mobile1 High Mileage 10W-40 with a Mobile1 Filter.
 
^I dont know why but for some reason mobil makes my motor sound real noisy. Switched to valvoline and it stopped :thumb:

I get the noise too, when I switched to penzoil for about 1500 miles I had no noise, but I felt the oil didnt last very long so I changed back to mobile1
 
Mobil 1 is good on a stock vehicle, but its been proven it won't protect as well as other brands. The zinc and phophorus numbers are a lot lower.

Edit: just read the attatchment.

Ive been wanting to try this stuff, but I dont like how it only comes in 5w40 in full synthetic.
 
You know what I think I'm gonna try rotella. Any suggestions on filter? I live in hawaii so theres no snow like you mainlanders got, not really cold ever either.

Then get some T6 10W40 and either a Wixx or OEM oil filter and you'll be good to go.
 
Any oils with a high zinc and phophorus, the file I posted above shows different oils that meet the requirements.
 
I think I'll try valvoline instead I didnt see rotella on that list. At least what I've been using has "mid" zinc levels.
 
so what would be the correct weight for a stock dsm with rotella?

I also heard that using this oil would be bad for the cat, not that I have one but I recall an sti owner saying it. good for turbo, bad for cat :confused:
 
Oh that would explain why I couldn't find any other weight. LOL Everyone else was saying you could get others.

There are other weight rotella oils, but the only full synthetic is the t6.

The 15w40 is the rotella T5, which is a synthetic blend.
