Years ago when synthetics were rediculous money i never used them now a days they are cheap. The difference in the cost of pennzoils 5w20 lowest grade conventional oil and their highest grade pennzoil ultra platinum synthetic is a total of $15 per oil change on the hemi if you do it yourself. Planing to keep this one a long time so the minor cost of a little extra protection doesnt hurt. I change myself because it only takes 20 minutes instead of sitting around a dealer all morning and most of all to know its done right. I have read about to many botched oil changes at dealers, why, because their most unskilled people do the oil changes probably highschool students on summer jobs that could careless about your new expensive vehicle.

Re: Engine oil question?

The major difference between Dino and Synthetic is that synthetic doesn't break down as soon as dino and it runs cleaner than dino. It costs a bit more but you get what you pay for. Your choice.

True about the better breakdown resistance for a quality synthetic using a good base. Not really true on the "running cleaner" part. Oil gets "dirty" mostly because of contamination with combustion byproducts, which happens regardless of whether the oil is synthetic or conventional.

Synthetic does run cleaner because it doesn't leave as many deposits as dino does.

Synthetic Oil Pros and Cons - HowStuffWorks

Don't believe everything you read on the Internet . The "deposits" you are referring to are oil breakdown byproducts and heat coking. They aren't "dirt" per se, but oxidation of the existing oil. You can have perfectly clean, but entirely broken down oil. It happens often in hydraulic systems.

Hence, my agreement about a good synthetic not breaking down as quickly as conventional oil. "Dirty" or "cleaner" to me implies less external contamination, which is not related to the synthetic vs conventional debate. If you're going to equate "cleaner" to "less breakdown" then saying synthetic oil has less breakdown and runs cleaner is saying the same thing twice, as if they are two different features.

So your saying that your right and these sources are wrong?

Re: Engine oil question?

This is one of those topics your mother told you not to discuss in public, like sex, religion and politics.

Re: Engine oil question?

I totally agree on the dirty oil/clean oil comment. Dirty oil is a product of the outside environment
