Synthetic Vs. Regular Oil in a 2.2

Here's something else to think about...
"Engine wear actually decreases as oil ages. This has also been substantiated in testing conducted by Ford Motor Co. and ConocoPhillips, and reported in SAE Technical Paper 2003-01-3119. What this means is that compulsive oil changers are actually causing more engine wear than the people who let their engine's oil get some age on it."

Your car calls for conventional to be changed when the oil life monitor says to. Currently you're changing it at 3,000 miles which is way too soon, so going by the monitor would give you the longer oil change intervals you desire and you don't have to spend the extra money on synthetic. Only reason to use synthetic would be for even longer oil change intervals beyond when the monitor says it's time. I don't see why people continue with the ancient practice of 3,000 mile oil change intervals. Has oil and engine technology simple not advanced one bit in the past 20 years?

Its possible I am but thats 5000 miles on oil. Granted I will check it and see what its looking like at that point. But I worked at chrysler when they first suggested 5000 mile oil changes. Should of seen all the 2.7s that were all coked up with oil inside. They were actually blowing engines due to the build up of oil. The ecotec is different yes. But ever since seeing that im going to stay under the manu's recommendation.

I have yet to see anyone provide any substantial data backing up a 3,000 mile oil changes making an engine last longer. Everything I have seen states they are unnecessary and potentially results in more wear.

I been using full synthetic since i got the car. i drive it kinda hard, i want hard good oil. i go by the dash myself. i think i change the oil maybe like every 10k miles. i even checked the dip stick a few times and the color still looked good. i pay 45 bucks for a full synthetic oil and oil filter change including labor. thats a good price i think.

Well, if you actually look at the data from that study I linked to, it backs up the results from the testing Ford and Conocophillips did. The most wear occurred within the first 3,000 miles and was a fourth that from 3,000 to 6,000 miles. So this would indicate that you're actually keeping your engine in the area of most wear by doing 3,000 mile oil changes.

How would it result in more wear..? That doesn't even make sense. I think you're looking way beyond the simple fast of, oil prevents wear from internal parts running at a high rate, no questions asked.
In fact, I work at a ford dealership and even the veteran mechanics will say it's a load of ****. I've seen cars come in with motors that are full of sludge from what you're claiming.
To each his own, though.

its not because of the lubricating properties that you change it at 3-5k. Yes the oil is still doing a great job with lubricating the engine. Its oil contamination from the combustion cycle, bearing wear, and other little purities that will saturate the oil.
The reason why you change it at 3-5k is because the oil is starting to lose its acid neutralizing ability. and it cant hold much wore along the lines of contamination. If the oil cant suspend these contaminants, they will deposit themselves inside the engine as SLUDGE.
some of you people amaze me with your misinformation. Half of this board must be around 18.....

^You're a little late...it was posted on page 2..
Here's the main thing....everyone has their own ideas and opinions on how long they can/should go between oil changes...no single person will change another persons mind in most cases.
I for one am a believer that you can go 5-10k on conventional oil in some cars (my old Saturns I owned with the 1.9L they burned oil so I would just add every couple weeks...then at 10k I would do an oil change and they last fine....engines in those cars are still doing great to this day). My dad had a 1984 Cavalier Type 10 that he stopped changing the oil in all together. He only replaced the filter and topped off the oil every so often (I believe he did it once or twice a year only)...the car lasted until the early 2002 or something like that...18 years until the car finally crapped out and it wasn't due to the engine failing either....I forgot to mention my dad was a mechanic for a number of years as well so he wasn't clueless when it came to cars.
I know in those cars for sure there wasn't that much contamination in the oil when I did oil changes...there was probably the same amount as I find in my car with a 6k oil change...

Makes sense though, if a car loses oil and it is topped off, you're replenishing the additives and putting more life back into the oil. The concern at that point though would be the oil filter, which would still need to be changed regularly. I recall on BITOG people installing some crazy oil filter setups in order to pull extreme oil change intervals. You can learn a lot over there -- more than you'd ever want to know about oil.
And I agree...this is a topic that we could never meet a consensus on. Do what you want with the information and make your own decision.

I have also tried:
Valvoline fully synthetic (x1)
Castrol Edge fully synthetic (x1)
Royal Purple fully synthetic (x3)
Mobil-1 Extra Protection fully synthetic (Rest of the time)
ACDelco filter from the dealer.
I do try other fully synthetics sometimes just for fun, but at the end of the day Mobil-1 is what's in my car.
