Google rotella and you'll find plenty of reading.



Wal-Mart. $16/gallon
Most all late model diesels come with cats and they use Rotella. It might be bad for our stock cats over time, but I wouldn't worry too much about it harming the metal substrate cats that come in the aftermarket downpipes.
Walmart around my house sells Rotella 15/40 for about $10 a gallon.

As long as the oil meets the API SM rating, you are good. The Starburst Energy stuff is only tree hugger stuff. It will have nothing to do with your warranty. I've been running Rotella in my 08 since the 250 mile point. And it has been in my 05 for years and its all that I run in my built motor on my 05. I have no plans to change what works.

Don't worry about using an energy conserving oil. Oils with this designation are usually meant to improve fuel economy (i.e. they'll probably have a lower viscosity). I'm assuming manufacturers list this designation in the manual so you'll get the advertised fuel economy.

What would you rather have, better engine wear protection or better fuel economy? I can't comment on the rotella though, never used it. I am tempted to give it a try.

I have never used Rotella in my cars, because I have been worried about damage to the cats (is it the zinc additive?). However, I have used it consistently in my motorcycles (without cats) with great success for the last 3 years. Every time I change the oil it comes out, not golden, but not black either. brownish. I figure I probably don't have to change it so often.

Lots of motorcyclists use Rotella for the same reason that, I guess, you guys have found out; the wear inhibitors seem to be much better than in other oils.

I prefer the 5w40 to the 15w40, because the moto engine didn't seem to idle as smoothly when cold.

==edit==
Oh, and I meant to say that, you can use Rotella in motorcycles with wet clutches because it is not energy conserving. If you use an energy conserving oil in a bike with a wet clutch, the clutch can/will slip. That is why you don't use energy conserving oils in bikes with wet clutches

Rotella isn't targeted at the passenger car/truck market:
- What Do You Drive?

And they have changed their formula for passenger diesel trucks. The new 'triple protection' white bottle has reduced levels of phosphorous and zinc. The blue bottle has the highest levels and isn't recommended for newer passenger diesel trucks.

Changes to oil due to emissions changes for passenger vehicles:
- Answer Column

And I am one of the people who uses it (Rotella-T blue bottle) on my motorcycle.

Thank you for bringing this up! I noticed this recently too but haven't mentioned it to anyone yet. Yes, the newer Rotella T synthetic is SM rated and therefore, it has less ZDDP. Booooooooooooo!!!!!!!! ZDDP for life! (IMHO).

I ran it for 200,000 miles in my 03 Duramax and never had a problem with the cat. I then used it for 125,000 miles in my 05 diesel Excursion. It also had no problems as far as the cat goes. I would use it in my 08 F450, but you have to use DPF approved oils in it. Regular Rotella doesn't fit the bill yet. I know ALOT of passenger diesel truck owners, and about 95% of them use Rotella oil. I have used it in all of my Subaru's and they seem to like it. I even know of a certain shop (with LOTS of knowledge on this stuff) that highly recommends the use of Rotella in our cars. They even use it in their record setting time attack car week in and week out.

There is no doubt in my mind that I would be using Rotella synthetic 5w40 in my STI, if it weren't for the cat issue. If you don't care about replacing your cats or you want to go catless, I'd use that oil in a heartbeat. The price is right and the protection is great. I used it at a trackday recently where my bike was seeing 8000-12000 rpm for 20 minutes at a time, and it burned not a drop of oil. And when I changed it afterward, it looked fresh. That's an A in my book.
