i take my car to the dealer for oil change...and i bring my own oil which is MB1...if i switch to royal purple will they honor it?? thanks

 

I went from mobil 1 to royal purple and my lifters ticked alot louder than before. Also when I was logging it with evoscan my motor was getting 8 counts of knock. I just switch back to mobil 1 and the knock went away..

 

now that is wierd...

 

Thats your response? Seems abit childish, given that you're so dedicated to the Royal Purple brand. I'm sure they have a need for people of your experience on their promotional staff.

 

Knowing Mitsubishi, they'll use whatever oil you provide for them. Come time for any warranty work, I'm sure that they'll use that against you in some form or another.

 

really??? so that mean royal purple is not that great. how about redline, is there anyone here run redline in their car? how is it compair to m1?

 

I use Motul oil 300 V 5W30.

 

Testing has shown Mobil 1, Amsoil, Redline, and Motul are ALL better than Royal Purple. Royal Purple sucks.

 

That's kind of a overgeneralization.

Different oils will behave differently in different engines. What we need is an impartial study comparing different brands and weights in Evo engines... not just people throwing out "I heard it's supposed to do this" or "My buddy has noticed this".

We're smarter than to accept marketing claims, hearsay, or non-scientific placebo-effect feedback that people believe they get when changing oils.

FWIW, I use Mobile 1 because that's what the manufacturer designed the engine for.

 

where did u get this asinine info from? i want to see proof.

 

i've been using RP oil for the past 6 months and i have no complaints at all

 

ha, ha! i went by the service department of my local dealer one time and there was an evo there with a spun bearing wanting warranty work. the service guy was telling me about it and said it probrably won't be covered because when they drained the oil it looked really black! i was like, if you put new oil in an engine, drive it 2 miles, and drain it, it's black, unless the engine is brand spanking new. gotta love techs!

 

Sounds like you didn't break you car in properly

 

Cue some 'tard posting the MotoMan link for 6.023x10^23rd time...

 

i used royal purple oil since 2002 never had a issue with it until few months ago when royal purple chnaged there sticker lable i think there oil also went down because after i flushed it ,it came out black, i change oil every 2,500k i gave 2 more chances after tht and it also came out black burned so i said *** it n changed it back to mobil 1, after flushing mobil1 2,500k oil came out normal, so now im back with mobil 1, i also have a friend who own a cobra mustang n same thing happen to him so it wasent my motor or nething like tht had to be the oil, not bashing on royal purple because they made great oil but the new formula def changed for worse!!!!
