just changed all my fluids to synthetic it runs beater than what it was with regular oils it is the best investment i ever made yes it cost a bit more and it is well worth it. love the performance out of the car now it is like it has a new personality and 0-60 responce picked up quick fast and in a hurry and the gpm jumped up as well. i have e3 spark plugs in it befor i did the fluids it ran ok. now it is klike it wanted the synthetic fluids from the start when i got the car those three items i mentioned are the best investment i ever made!!!!!!!!!!!!!!!

 

just oil, plugs, and trans fluid? made your car more responsive? im asking cus soon i gotta go through all this stuff and figuring out if its worth it.

 

synthetic engine oil does not have anything to do with making your car more responsive. however, i use it in mine and i love it. helps a ton in these cold MN winters. as for trans fluid, i can see it giving youSLIGHTLY firmer shifts but not much more than that. i've talked to many mechanics aboutthat and they all say it doesn't make much difference. plus,the change interval is so long anyways, i'm gonna stick with conventional fluid.

e3 plugs sounds like a good swap to me. i will pry use them when it's time for a change. let us know in the future how they work. good luck!
