Syntec Oil vs Regular Oil

[amadriga]

Thanks Jackassi

Is that the preference order??

Is there some specific good mark (Valvoline, Castrol, Penzoil???) that you prefer or recomend??

Actually I'm using Valvoline Racing 20-50, I heard Valvoline has the sympower, It sounds like a good oil.

Yes along with order of cost.

I've always used Mobil 1 or Penzoil synthetic but they're all good brands out there. More of a personal choice.

20w50 is way to think for a small 4cylinder, it actually reduces power & doesn't protect as well. I used to run 20w50 during track session & found that thinner 10w30 improved time by a few tenths.
0w30-5w30 - year round
10w30 - summer
10w40 - high mileage / ticking engine

Every new motor I have ever run I changed the oil the first time @ 1000 miles and then @ 3000 miles then I switched to synthetic. As far as the brand is concerned...more or less a personal preference, but my experience in life is you get what you pay for...if you see $2.00 oil your buying just that $2.00 oil
