where do u guys get the royal purple? i want to try them as well.

 

Pep Boys... about $6.50/qt

 

whats the difference... why change? feels smoother... more power... what?


i use mobil and i think its fine... what data is there to prove that one is better than another?

 

sry.. i dont want it to sound liek an arguement.... just wondering...

 

don't think i have pep boys around here.. sucks

 

just how the oil comes out at the oil change... see if Royal Purple holds up like Mobil 1 does or better.

 

You'd be surprise. Here's a link to one recent thread.

even better mobil 1 10w/30 extended performance and mitsu filter

 

why do you guys use the oem oil fiter and not a k&n or Fram?

 

+1 That is what all my cars use.

Mobil1 10w30

 

I use OEM because I can get one for less then $5 and I really see no difference between the mitsu one and k&n/fram... except mitsu doesn't have a grip or nut.

 

How about Using on of those Ralliart White Oil Filters that go for $20 some bucks

 

Im using royal purple, but I change the filter every 1500-2200 miles and just refill the lossed oil then change the oil out on the third filter change. I have done this on the last few cars and bikes I owned and the oil NEVER gets dirty at all. It still stays purple even after 5-6k miles.

 

As long as the oil is full synthetic and a brand I know and trust there is no difference. I've been mobil 1 since I got the car but a while back advance autoparts was selling penzoil platinum synthetic buy one get one free. I've been using it for about 2000 miles and notice no difference. Even mobil 1 is switching from a group 4 to a group 3 oil which is the same as pennzoil platinum and castrol syntec. Group 3 oils are not fully synthetic but highly refined conventional oil.So really there is no difference. I believe royal purple and Amsoil is still using group 4 full synthetic oils.

 

Royal Purple and K&N Filter FTW
