Do some research...plenty of forums discussing this same question can be found on google. Here's one Bob Is The Oil Guy - Forums powered by UBB.threads™thanks guys my friend told me to use royal purple but then some one at work said not to that its not good. so im not really sure. what to do.
Royal purple is good the only downfall of it is that it uses molly which I guess can solidify and clog oil passages. That's just what Ive heard but as long as an engine has good oil ports and flow there should not be a problem. I use to run it in my old sunfire but after hearing that my paranoia kicked in and I switched to amsoil which is very good also but moneys been tight lately so I switched to mobile 1, seems to do just as goodthanks guys my friend told me to use royal purple but then some one at work said not to that its not good. so im not really sure. what to do.
Speaking of a great help, just threw on a Fumoto Oil Drain Valve. Here's where I got it from, QWIK VALVE: ENGINE OIL DRAIN VALVE MADE BY FUMOTO: THE BEST WAY TO CHANGE THE OIL QUICKLY AND EASILY! Draining oil is a breeze. Also, if you over fill a little, no prob. Want a little out for an oil sample/analysis, no problem.thanks everyone. everyone has been a great help
Can you find the quote where ntechnic recommended 5w20 for an MS3? I find it hard to believe that he would recommend a 5w20 for a boosted car.I just put in 5w20 fully synthetic German Castrol Syntec, based on a recommendation from ntechnic
Personally, I wouldn't run anything but 5W-30..that's what the manufacturer recommends (they should know best)...and I use Mobil 5W-30 for speed 3...in fact I've pretty much used just Mobil 1 for all my cars dating back to the mid-80's...it's a great product!I have used Penzoil Platinum in my other cars with excellent results. However my first oil change I went with the walmart Supertech Full synthetic. Cant beat the price. So far seems to be holding up well, I read good reviews about it so gave it a try. Much cheaper at $17.50 for 5qts.
Like you, I have been a bit confused as to what oil to run though. No one on the other forums seem to think its good to run the 5w-20. Also the Mazdaspeed oil cap says 5w-30, so I went with that. However a good amount of peope say we can even use 5w-40, because it will reduce the turbo smoking issues. Rotella full synthetic 5w-40 has some great reviews so I have contemplated running that as well.
