ok so im changing my oil tomorrow, i want the best but i dont want synthetic. i used sythetic b 4 (royal purple) and my car dosnt like it...it burns it bad. so i switched to regular oil n its good as new never low on oil no more! so my question is this:

what is a good non synthetic oil for me to use?

SuperTech, Pennzoil, Valvoline...

What about mobil 1? I used that in my last car for a long time and never had any issues. I also spent the money for the $12 mobil 1 filter too.

Mobil 1 is synthetic.

As for "burning it" synthetic will get into places conventional oil won't. Therefore it may leak out of the weak spots in your seals, go by the old hardened valve seals, worn guides, piston rings, etc. that conventional oil simply doesn't let you know about. This is why switching to synthetic gets a bad rap in higher mileage/older engines.

I would think any common name conventional oil will do. I have generally used Mobil or Pennzoil. I had bad luck with Valvoline, but it may have just been that particular engine didn't like it. 3 quarts gone in 75 miles worried me a little. Drained put Pennzoil in, and it never dropped. May have been a fluke, but I never risked Valvoline in that engine again. But it kind of added "truth" to my teacher's advice to pick with a brand and stick with it. That was 26 years ago tho. I hope they are a little closer on the playing field now.

I may be wrong but I believe Mobil 1 has some blended oils as well. Personally I use Mobil 1 5000 but change it every 3k. At $3 a qt. I doubt its a full syn.

The 'Clean' Series aren't FULL synthetics, the FULL synthetic series of Mobil 1 will say Synthetic

That would be Mobil Clean 5000. Not a blend. Anything with Mobil "1" is synthetic.

Heck, you can get Motorcraft too. About $12 for 5 quarts at Wal-Mart. Another great oil.

so you guys are saying all conventional non synthetic oils r the same....

I've always had good luck with Valvoline personally. Years ago I tested 20-50w oil from different manufacturers in my old 250cc Honda dirt bike and the Valvoline oil held up really well.....
If you want to go cheap on the oil but want great protection ad some BG MOA to the oil....

No biggie, you wouldn't be the first.

They may not be identical, but they are all sufficient assuming they have the latest rating.

The current oil standard is "SM." This is a very strict standard.

blue streak, I know you said you specifically don't want synthetic due to problems, but I have to ask... which synthetic did you use? I used Mobil 1 religiously until it started disappearing on me. My car now has nearly 120k not-so-friendly miles on it, but it's been cared for enough where it shouldn't be losing oil. I switched to Castrol Syntec because I always had good luck with regular Castrol GTX in other cars. With the Mobil 1, I had 3 quarts missing after 5000 miles. It was enough where hard corners would flash my oil light. Castrol Syntec, I'm down less than 1 quart in the same interval. Food for thought.

So synthetic is not good for high mileage cars? I was tinking og going to a full synthetic oil. I have about 170k on my car, do you think that would be good?

the synthetic oil itself won't hurt your engine. but it may expose existing flaws

It depends on how good of condition the internal engine is in. I switched to full synthetic in the low to mid 80,000 mile mark. No issues. Some people switch at 40,000 and have problems. Issues being leaks and so on.

Most of the time problems are the result of poor past maintenance

oh ok I see what you are saying, thanks for the clarification.

FAIL.

And if your car is burning oil, it will do it regardless of what kind you use. Fix your problem, fill with synthetic, continue about your business.
