Oil Change

I send my opil off for analysis to see what interval works best for me. I'd rather rely on science than some made up oil standard that has been around for decades. If the manual calls for 7,500 miles, tehn why doubt it? Hell, I run 12,000 miles in our Envoy and still get a great analysis report.
I run a full synthetic oil like Mobil 1 and use Lube Control, so that gives me a cushion and measure of comfort.

They is alot of factors that go into oil changes. How is it driven, temperature, and what type of oil. To me if your using a synthetic you can go longer between oil changes, compared to conventional oil. To me these all factor in to get the oil change at the right time.
Manual says to change oil every 4 months/5000 miles if one of the following conditions exists:
- Repeated short-distance driving
- Driving in dusty conditions
- Driving with extended use of brakes
- Driving in areas where salt or other corrosive materials are being used
- Driving on rough or muddy roads
- Extended periods of idling or low-speed operation
- Driving for long periods in cold temperatures or extremely humid climates
- Driving in extremely hot conditions
- Driving in mountainous conditions continually
Since none of these really apply to me I will stick to the 6 month rule.

Change the oil according to mileage, not time. And use the weight specified in the manual. If you use the wrong oil and have a problem, goodbye warranty service. Also, the oil a manufacturer recommends a certain weight based on the engineering of the engine, particularly things like hydralic lifters, etc.
I took a previous vehicle to an oil change place ONE TIME, and after they put the wrong weight in the lifters ticked. worse, after changing out the wrong oil, the problem never went away.

This doesn't work for everyone if you stick to the owner's manual. There's no way I will see 7500 miles in 6 months (maybe 5000), so I'll stick with 6 months per manual.
Exactly.
Had the dealer change the oil in my CX-9 last week. Today I checked the tire pressure in all 4 of my vehicles, and the CX-9 had anywhere from 41-44 pounds in each tire! The service department must have done this when they did the LOF, as I check all of my vehicles at least once a month. WTF?!

Except, TIME doesnt wear out and contaminate the oil. Miles do.

I use synthetic and change my wifes every 5k or twice a year, whichever comes first.
I just did an oil change myself, using a Mityvac oil extractor. I extracted only 4L out. To make sure I got everything out, I also opened the drain plug, and there was very little that came out (may be a few fluid ounces). Then I dropped the oil filter. There, I got another half a liter of oil out. So total oil I got out of the 2010 3.7L engine was about 4.5L which is far less than what the manual says of 5.2L. Anyhow, it doesn't bother me. Now I know that I can just use the Mityvac to do oil change and not to have to mess with the oil drain plug. It really sucks to do oil change on Japanese cars as their oil filters are at the bottom. They need to learn from the Germans and put the oil filter on top! I can change oil on my bimmer without crawling under the car.
on some cars, sure. definitely not on all of them.
i think the CX-9's filter location is perfect; don't even have to jack up the car to change the filter, and i don't need to fit my hand in past hot engine parts to reach it. *shrug*
Hey everyone,
I just took my CX-9 to the dealership to switch my oil over to amsoil synthetic, the vehicle only has 1900 km on it, just picked it up last month. The service writer called me and mentioned that the shop foreman said changing to synthetic before the first 8000km is not recommended because apparently the engine hasn't broken in yet. Goes on to say that the synthetic oil will not allow the seals to seat properly and I'd be looking at leaking oil in the future if I switched before the "8000km engine break-in". I only want whats best for the new car, and apparently I wasn't taking the right approach so I'd like your opinion on this.
Thanks guys.
