NA Spark plug questions...

[GC-2nr]

What's the best plug to run in my GC4? Currently running NGK V-Power's....I have run genuine Subaru plugs that are also made by NGK, but I havent noticed much difference between the two as far as efficiency/performance....

Did some reading in the NGK catalog here at work, I think im going to try the G-Power platinums for the first time, I change my plugs pretty frequently so I dont see a need to put in iridium plugs, which seem like a long-life version of the platinums. So G-Power it is, unless anyone can convince me of otherwise.....

im sure theres plenty of peeps on here that can reccomend a good plug for your turbo engine, i on the other hand am probably SOL, being that im asking a bunch of turbo-heads about NA stuff

8/3/08- Installed the new NGK Gpower platinums, new oil press.switch, and new coolant temp sensor, cleared memory. Its running awesome right now, lots of power, no hesitation. Put some Shell premium fuel and a bottle of Techron fuel sys. cleaner in the tank.

Needs an oil change- have been running Mob.1-5w30 for 2 years, but i heared a few sob stories about running synthetic and it caused spinning of the rod bearings or something? Should i consider a different brand?

hey MOSC, whats your take on my oil question?

now thats regular conventional oil, i was told that once you run synthetic, you cant go back to conventional, is that true?

[mosc]

no, it's not true
