Engine Oil
I switched to Mobil 1 about 15,000 miles ago since I do alot of in town driving. I get the oil changed every 5,000 miles. I noticed the day after i got my oil changed the oil seems dark and looked used up. I know that dark oil is good because that means it is trapping particals but why so soon? Is that a problem? I switched over to synthetic when the car had 70,000 on the odo and haven't had any problems with oil level. Just wondering...i thought it would be a least somewhat clear. Thanks

I believe it depends how its changed some people use this stuff to flush everything out of the oil system and some don't, its not needed but jus an option. I got my oil changed today at walmart. But yeah depending how its done you may drive down the street and it turn dark or you could drive for a month before it turns dark but its fine either way as long as you ep enough in there and get it changed when you need to.

dark color is good, and does not mean anything. It depends on your driving style(normal/severe) and time (your should change your oil once a year regardless of milage).
But I'd say 5,000 is defiantly OK even if your driving style is severe, I am sure you can push it for more.
I personally use Mobil 1 Extended Performance (guaranteed for 15,000 miles or 1 year) and change my oil only once a year ( I only putt 9-10K miles a year). You also need to buy a good oil filter.

Thanks for the replies. Yeah, I would like to push the oil changes a little longer because at $45 a pop it gets expensive and I put alot of miles on my car. I would think by the time 3 oil changes rolled around the engine would be flushed. Who knows...thanks

40 to 45,000 here.
As for the Wal-Mart question, how do you guys think wal-mart makes such a profit. 1.)Undercutting manufactures and threaten they won't carry their product if they don't sell it to them cheap enough.
2.) Cheap arse labor. (A typical mechanic can make decent money, how much do you think the average Wal-mart car tech is making)

for all you people who drive mostly highway and put a lot of miles on their cars each year, I am pretty confident that even regular Mobil 1 ( not even Extended Performance) is good for 7,500 miles.
With Extended Peformance(EP), you can safely go 10K miles if its mostly highway. In fact, Mobil 1 EPguarantes 15,000 or 1 year. So even 15,000 is probably OK, but I would use an oil test to verify that. But 10K highway miles is definatly OK with Mobil 1 EP.
if you pay extra money for synethetic oil, you might as well take advantage of extended drain intervals to make it worth while....
I did not even mention Amsoil.... that is guaranted for 25K miles / 1 year

Have you tried Mobil 1 Extended Performance? It might be good for 20K miles. I am trying to figure out if I should continue using Mobil 1 EP or just regular Mobil 1... I only put like 9-10K miles a year, so I have to change my oil once a year regardless of millage....

3 month/3k is a myth and waste of time and money even if you use regular oil.
3k or 3month with Mobil 1 is a total waste of money

I do mine between 6K and 8K with Mobil 1. I usually do that between 2 and 3 months.

I been using Amsoil 5w 30 since I bought my car. And Royal Purple in the tranny. I change my engine oil about every 2 years. Oil filter (Fram Duraguard) about every 1 year. It runs smooth. Currently have 75,000 miles on my CLS.
