i'm just wondering whats the difference between full synthetic and synthetic blend? is the blend more like Oct. 89? its a mixutre of crude oil and syntec?

 

Synthetic blends are crap and are a marketing scheme. They don't work any better than regular conventional oils. True synthetics such as Mobil 1 or Pennzoil Platinum are a Group IV oil (which contains a better base stock oil than conventional), not like the "fake Group III oils that can legally call themselves synthetic like Royal Purple oil.

 

Royal Purple isn't true synthetic? hmm...also does Quaker State make any synthetic made for cars? i know they have them for trucks and 4x4's...but i couldn't see any for cars.

 

Nope.

They don't make a "true" synthetic.

 

why do you hate royal purple

 

I don't hate Royal Purple, but if for the same price you can get a TRUE synthetic...why not?

 

not trying to start a fight but why is it not a true synthetic

 

My personal choice has always been Mobil 1 for synthetic and Castrol GTX for regular dino oil.

 

What About Amsoil and Red Line? True Synthetic?

I started out using Amsoil for the 1st 2 years of racing - then switched over to Red Line for the past 2 years.
I noticed that all of my competition was running Red Line - So I swapped over.

I also use Red Line MTX and Power Steering Fluid in my race cars and tow vehicle.

 

Becasue true synthetics are Group IV oils and Royal Purple is a Group III oil. Group II oils are severly hydrocrakced oils that can be called synthetic.
