Some people will tell you that premium gas is a waste of money. Maybe in some cars, but with a turbo its better to be safe and use synth.

Not all cars have a pinwheel in the hottest part of the car and then spin it around 50k-100k RPM, whip up oil and return it boiling hot to the pan. But mine does. So I use an oil that can take the heat.

 

Did 5w30 dino oil until 7500 changed around 2000 except the last one at about 1500, just switched to amsoil 5w-30 and it seems to be pretty happy.

 

Was on dino for the first 5k miles then switched to 5-30w Mobile 1 synth. Just switched to Amsoil. I dunno the for the price i figured that it must be pretty good. But I then heard that Amsoil has ummmmm something bad in it. Addititives? Crap I can't remember what they're called. I dunno thinking about trying Redline, but I think moble one is prolly the best bang for the buck. I don't like the idea of changing my oil every 3 months and paying 65 dollars. Not sure that Redline or Amsoil is worth that much. Never had problems with Mobile one synth.

how does non-syn with lucas compare to just synthetic?

 

lucas tends to foam at higher rpm's, so beware

read this not so great independent analysis: http://www.bobistheoilguy.com/images/lucas/lucas.htm

 

It is easy to do your own oil. It costs about $20 for the oil and $5 for the filter.

If you have any mechanical inclination go ahead and try it out for yourself. Over the life of your car you'll save a lot of money and get some personal satisfaction out of it.

hot dang...why is everyone recommending lucas and suplying them then? what is considered "high rpm?"

 

I used 0w-40 Mobil 1 for the WRX for a while, but switched back to 5w-30 since I use it for my Accord. My AE86 is on Amsoil.

 

royal purple 10w-30

 

on my old '02 WRX, and now on my '04 STi, I have always used (after an 8k mile break-in using dino oil), Redline 10W40 full-synthetic.

 

On my old honda Castrol GTX DRIVE HARD 10W-30 now on my 05 STI Mobil 1 5w-30, getting change every 3K.

 

what if 5W30 fully syn is not avail should I go to 5W20 or 5W40? I got this coupon for buy 4 and get 2 free for valvoline full syn, but kragen does not carry 5W30 in full syn from valvoline and its on sale for $3.99 a qt!!!!!

 

anyone?
