O how wrong you are, some synthetic oils are man made some are man made blends and some are dino oil run through an extra refining process. All 3 will say 100 pecent synthetic on the bottle. VERY VERY few are acually man made. I run amsoil it is man made.

i can get 6 quarts of regular oil for 1 quart of synthetic...

so... synthetic = bad, money = good

if your not a lazy ***(as alot of these people here are) and do your own oil changes(like me) go synthetic. i take it a step further and get the Mobil1 filter too. go to there site and read about it. it can filter out the aids virus. seriously. filters down to 10 microns @ 95%.

synthetic is bad for engine break in.

I have always used regular Castrol GTX 10w30. I change my oil a lot though, probably every 1,000 miles, give or take a few depending on how hard I drive my car.

slowcivic

what filter?

beerbongskickass

AC Delco is what I usually buy, they are like 4 bucks. I would use a Wix or Purolator also, just as long as it's not a Fram/Penzoil.

slowcivic

thats what i used to use. the Pure one purolator.

synthetic doesnt lose its viscosity. regular oil gets thin and watery after repeated use.

well, yeah...i know that synthetic is a better quality and i always use it on my turbo crx. mobil 1 full synthetic and usually a K&N or Mobil 1 oil filter. I still change my oil like every 2500 miles. i dont even go to 3K before i change it now. i know its more money but i'd rather be safe than sorry. why do people cheap out on oil...thats like the blood of the engine!?!?! does it matter? i mean if you do it like BBKA then thats different cuz at least he changes it like every other week and why do people say its BAD for the motor? i've heard that before on here...
