Royal Purple, better than Shell Rotella T6 5w40?

[Smurftastic]

I am a big fan of the Rotella T6 5w40 with Purolator PureONE filter combination... and have been using this for a veryyyy long time. Good price.. great quality.

Maybe I'm getting a crazy whisker under my nose, but...

Anyone think Royal Purple is moar bettar?

Nope. Been refereed to as foo foo juice on here. Plenty of UOA to back that claim up too.

Oh Jesus did you just open a can of worms......

**** no. let me get a swig of that whiskey.

1. Wrong forum. Banal oil discussions belong in the Service and Maintenance forum.

2. Which Royal Purple? Royal Purple's 5w30 is indeed foo foo juice. The 5w40? Not so much. "Proving" it's better than RT6 is impossible for anyone outside a major auto maker or oil company. Got enough cash to put a dozen engines through life cycle simulations on a dyno in an environment chamber? I didn't think so. All RP products are overpriced IMHO.

3. Rotella T6 is a "fleet" oil meaning it meets the requirements for both gas and diesel oils. The thought being that operators of commercial fleets can reduce their inventory to just one oil.

Bottom line, even heavily modified turbo EJs will live as long as it's possible to make them live on RT6. Any problem which another oil will purport to solve is a result of some other deficiency in the design, not the oil and an oil based fix is therefore a band-aid. The one possible exception to this is very cold temperatures, but since you live in VA that's not a problem for you.

My apologies for the wrong area.... looks like I was already on the right track using Rotella T6

[ByeBye4g63t]

I just changed out the oil in my car with rotella t6, and the car seems like it runs "smoother". My buddy also took notice, commented that it seemed less noisy. I'm sure it's all in my head, but so far, thumbs up for rotella!

^^^^^this is actually very common for people who switch to rotella t6. So its not in your mind.

ALL multi grade 'rotella' oils are rated for 'mixed fleet' use(they carry SL, SM ratings)....means they can be used in any gas engine

this is a common misconception about THESE HEAVY DUTY, non-girly man oils

[Smurftastic]

Btw, for those who use Rotella T6, I can't find any better deal than Walmart.. never more than 21 bucks for a jug of 4 quarts. But because Walmart only carries Fram oil filters.. go someplace else for those.

[AspenScoob255]

^^^i agree, Wal-Mart=Winning!!!! When buying T6

Indeed, because girly men are not coo

I to had noticed the smoother/quieter operation. Glad its not just in my head.

I also used RP ONE time.....never again. I change my oil religiously every 3k miles, the term "purple koolaid" is about right. It drained in the aforementioned consistency (slight exaggeration).

This is the same thought I had when I switchedto T6 in my 04 WRX, but did not gave a second thought about it until I saw this reply.
Glad I am not the only that noticed this.

lol man oils. That just made my night.

[BoostinChick]

It's moar expensive than T6, I can agree to that.

[DarkKnightBaku]

+1 for rotella t6 MAN oil!

[WhatTurboLag?]

t6 pr bust. anyone that even thinks royal purple is good should just sell their car.




now the ultimate question, i live where it gets cold (chicago), would a 5w40 be too thick for winter months? idk if i should switch it out to something else in the winter.

[lyellowdragonl]

Will be trying Rotella t6 for my next oil change. I have been using Motul Racing oil 5w30 and loved it. Hearing good reviews on Rotella, I might as well take a shot at it. If not ill be going back to my trusted Mutul

the t6 has a pour point of -49°F.....as long as it does not get within 10°F or so of that temperature it is fine

chicago should be fine....I grew up in northern illinois and dont think it would be an issue

if you are worried get some 0w40 M1(-65°F pour point) or 0w30 'GC'(-65F pour point) for that jan-mar period

Unfortunately, I was one of the guys that switched to RP due to Rotella(tried different weights) making too much noise at startup. I was curious why it did this since my sti sat for a day and a half. It just made me cringe when it sounded like a valve was hitting the pistons. I ran Rotella for 3 months till I changed to RP and it stopped right after the oil change. The turbo tends to spool up smoother with RP. Since I left it at the airport for 5 days and started it up...no noise at startup. However, it has been leaking through the valve cover gaskets and crank seal.

I ran RP for 2 years and never had that startup noise problem. More than likely with Rotella synthetic, the oil settled and little to none in the heads. RP leaves a film of oil up top and I'm guessing it keeps it lubricated. Just my observation. Everyone's different on their review.

Currently, I've changed to Amsoil synthetic b/c RP got to expensive. I can get Amsoil for $2 a quart less and it's been working great for the past year. I now have 160k on the odo and the car is still running strong. I've been sending the oil to the blackstone labs for the past couple of years. Looks like the car is still doing fine with RP oil and Amsoil.

In the next couple of months, I'll be installing a custom rotated kit. Should be interesting. We'll see how it holds up. Another guy around town is running a similar kit but slightly smaller turbine. He installed it at 150k and is now over 200k on the rotated kit.

Overall, everyone has a different experience with Rotella, RP and Amsoil. I'm in the southeast and the weather is different 1/4 of the year.

there is ONLY ONE rotella t6 synthetic oil on the market and it comes in ONLY ONE weight

5w40

and this has not changed in as long as I can remember...and the blue jug is hard to miss


If you 'tried different weights' you screwed the pooch...and didnt use the T6 which is being discussed here

the very VAST MAJORITY of people who use the t6 report it is QUIETER than other oils

LOL! Let me be more specific. I also have a forester N/A version as well, that's why I mentioned different weights. My fault on that...details details.

BTW, I don't screw pooches...I eat them in my country. Yummy for breakfast. I need a meal not a snack.
