Hey guys and gals,
Did my search first and couldn't find a clear answer, so I'll add to an old post rather than start a new one.
I just bought an '02 WRX sedan. If you look at the profile you'll see its pretty heavily modded. The car was purchased with 46k from a dealer in CT by it's second owner. It was completely stock at that time. I just purchased it from him with 47k and all the mods. He upgraded to an Sti and did the same mods to that. I paid 15k, a great deal I think everyone will agree. I only had to do an allignment, and now plan on doing some regular maintenance.
Since he only had it for 1k miles he didn't do an oil change. It was done at the dealership prior to sale, dealership told me it's dino. Funny thing is that Subaru mechanic told me that he has synth in his WRX, but that in all the cars he's worked on he has seen NO difference b/w dino changed every 3k and synth changed every 5-7k. I, however, would rather be safe than sorry and would like to upgrade to synth.
Is it too late to put in synth if it's been on dino it whole life? Plan on using a NAPA Gold filter (WIX) as I've always had good luck with them.
If I can change over, does anyone recommend Royal Purple? Found a good deal on a couple of quarts and also plan on doing a differential and tranny fluid change. I've also heard good things about Amsoil and Redline. Please let me know what you guys think as your opinions are greatly respected.
Thanks for all the help for the newbie.
