would it be ok to put royal purple syenthetic in my motor. i bought it recently with 1500 miles on it, is it safe to switch, also is a borg warner tranny any good.

Royal Purple oil is crap, despite what many think. If you're going to use a synthetic, run a good one like Mobil 1, Torco, Redline or Amsoil. A good mineral oil with an awsome additive package is a lot better than a mediocre synthetic with a mediocre additive package.

I'll second that^^^^^ in independent studies royal crap ranked way low in the 4 ball friction wear test under extreme pressure....now is that what you want in your turbo or supercharged NO2 POWERED WHEEL STANDER??......not me anymore whiped mains out in two motors and royal crap was in both.......NOW I run top of the line amsoil

thanks ill be sure to go with another one, but it would be ok uh, also what about the borg warner tranny they any count

atf dextron III / mercon will be fine or a synthetic based one will be fine too

How is castrol syntec thats whats in my car with a purilater filter? My motor is stock anyways though.

I lost a thrust bearing on Castrol Syntec. It's not as good as it used to be(which is true of many oils these days). The people I've talked to that have run Castrol in their race cars all say the same thing, more debris in the filter with Castrol than other oils. Castrol used to be the favored oil of older British cars and motorcycles that have some pretty severe lubrication issues involing cams and lifters, but recently Castrol has been killing them. What fails, or if, also depends on modifications. Performance engines place MUCH higher demands on lubrication due to higher thrust bearing loading from heavier clutches, higher bearing and wrist pin loading from higher compression and more power, more friction and heat from higher rpm/power output etc. What works fine in a stock street car may kill a high performance car.

Mobil 1 or Amsoil.

what about quaker state, is that a good one

quaker state isnt bad either. as for a t5 they are alright trany's when you dont have really much work to the engine after that they dont like to hold up very well. i have a pretty beafy one in my car and i havent had a problem. borg warner recommends gm syncromesh in the t5's or royal purple sycromax. the shifts get a lot smoother when you use either of those
