hi all, i just hit 175,000 miles on my baby, she is supercharger. i was wondering what kind of oil do you guys suggest. oil is like blood in a body, i want to best of my baby. i currently run castrol gtx high milage, is that a good oil or should i switch? also i dont want any synthetic oil

I used Walmart brand Full Synthetic with Purolator PureONE filters until I heard about Rotella T6, another heavy duty full synthetic.

Before I switched to synthetic I bounced back and forth between Walmart brand high-mileage and Havoline high-mileage. Was using WIX filters back then too.

I was using synthetic, whatever was on sale, for my 165k miles SSEi. I have been losing a quart of oil about every 1000 miles. I recently switched to super cheap Shell Rotella T heavy duty motor oil. Sold at Autozone in a 5qt container and a STP filter for $10.

My reason to downgrade the oil was I was going through 2-3 quarts every 3k miles, so where was the gain- I am always using fresh oil. Funny thing, my oil consumption has gone down after switching back to conventional oil.

Shell Rotella T is worth more than what they charge. It'* crazy. I'd use it in the bike if the weight was right.

Mobil Super Synthetic and a FRAM Xtended Guard filter in the car right now. (go ahead throw a fit at me for using FRAM, I'll still use it :P)

the world'* greatest oil means nothing without good filtering.

however, even the worst oil(of the proper weight/viscosity) still has to meet some decent standards. oil filters don't have such rigorous requirements.

which one is the Xtendedguard? as long as it'* not the caustic orange one or the one or two above that one, those aren't THAT bad..... but for the price, WIX(and it'* rebrands) and purolators are significantly better choices.



oh, i run pretty much the cheapest oil i can buy. either Supertech or Meijer branded stuff. Purolator Pure1 PL24011 filter. i'd like to move up to a synthetic, but no decent sales have went on at any of the local stores involving the weights i'm looking for.

Look at Rotella T6. It'* a heavy duty full synthetic. If its good enough to be put in super high-compression race motorcycles, it'* good enough for my car. It generally sells for $20 a gallon and it'* 5W-40.

5W-40 is a bit thicker than what i'm looking for... at least for this car.

0W-30 or 5W-30 is more along the lines of what i seek.

i do know that the people who use the T6 tend to love it. and $20 for 4 quarts isn't really that bad, especially since you can stretch out your oil change intervals a bit with good filtering, to the point of where it can actually be cheaper (or at least close) to run it than the cheapest conventionals.

$22 for 5 quarts for the oil and I think $6 for my Purolator PureONE filter (bigger one that fits), I run the oil life monitor twice before I change it. No problems and the car runs like a dream.

This with Supertech Full Synthetic too, so it'* 5W-30.

Valvoline racing 20-50 in my camaro and any other non stock engines.It has added zinc and zdp as far as i know it is only sold at Napa..anything else gets 10-30 and all get wix Racing filters
