i'm glad to see they acknowledge that dexron 6 is critical

 

I agree some company's would just let you use something and then you'd be out of luck.

but i guess they do have something that works on 05 or older models. i think horepower tv did a session on royal purple and changed out every fluidwith RP on a 00 camaro (i think) and on a dyno got like 8HP to the rear wheels. not sure about MPG's but if everything is lubricated better there should be a slight increase and anything is better than nothing.

 

yeah that is surprisingly honest of them. that makes me want to buy their products even more.
