Buick Century, Oil
#1 of 19 2002 GM oil change interval.
Mar 04, 2002 (2:56 pm)
Wife just purchased a 2002 Buick Century. While reading through the manual I found that GM recommends changing the oil within two tanks of fuel from when the "change oil" light comes on. No regular or severe service mileage intervals listed at all. I haven't talked to the dealer service dept about this yet but think I will have the oil changed at 3000 and 6000 miles and then change to synthetic and go 5000 between changes. I read somewhere that all 2002 GM vehicles are the same. Any comments?
#2 of 19 I would change to syn as soon as possible....

and just follow the change oil light. I personally would go longer. But each needs his own comfort level.
#3 of 19 MY Opinion

I have a 2000 Buick with the indicator light. About 19,000 miles now. Changes oil the first time at 4,350 miles and indicator had about 40% life. Changes to synthetic at that irtme and cahnged the filter at 6000 miles (Indicator had about 30-40% left) and changed the oil and filter when it had 12,000 miles on oil or about 16,000 total.
So, I basically ignore the indicator with synthetic oil. Oil analysis was fine, analysis after 12,000 was much better then with teh OEM oil at 4,350 but primarily due to the engine breaking in and you get the higher particles of metal and silicon in this period.
Anyway, it appears that with the type of driving I do the indicator would come on between 6000-7,500 miles.

I have a buick rendezvous. It too has the oil change indicator. In my manual, it says follow the indicator light and change within two fuel tanks, but if the indicator does not happen, must change at one year interval.....
#5 of 19 Here's how I was told to do it...

This came right from my mechanic, and the service manager told me the same thing.
1st change at 1000 miles to get all the break in lube out and change the filter. Change oil every 3-4 k until you hit 12k. Then switch to synth. After you switch to synth. you can let the car tell you when to change the oil, it's pretty accurate for synthetic oil, I wouldn't trust it on regular oil.
This is where all the posts for burning up oil come from. You have to let the rings seat to seal the engine up tight. Synthetic is too slippery for the rings to seat properly causing you to burn the oil. WAIT UNTIL YOU GET 12,000 MILES ON THE MOTOR BEFORE SWITCHING TO SYNTHETIC!!!!!!!!!!!!!!

This is a verbatim copy and paste from the website of Mobil 1, the biggest player in the synthetic oil industry, Q&A page:
"You can start using Mobil 1 in new vehicles at any time. In fact, Mobil 1 is the factory fill in all Chevrolet Corvettes, Dodge Vipers and Aston Martins. And all Porsche cars manufactured at their Zuffenhausen plant are lubricated with Mobil 1. So are all Mercedes-Benz AMG vehicles. One of the myths that persists about Mobil 1 is that new engines require a break-in period with conventional oil. Current engine manufacturing technology does not require this break-in period. As indicated by the decisions of the engineers who design these high-performance cars, Mobil 1 can be used in an engine from the day you drive the car off the showroom floor."
#7 of 19 torn between synth and dino for my triplet
Mar 10, 2002 (6:33 am)
Anyone out there have one of the new triplets, and weigh this decision? I'm leaning toward sticking with dino... not just because of the price, but for several other reasons. Obviously, price is a factor, but when you're talking a $25-35K vehicle, it's not going to be a make or break. Really for me to do the extended drain with synth, I would have to do the oil analysis 2-3 times to feel comfortable. Those I've talked to, who have done the analysis, tend to get between 6000-7500 before they need to change oil. I have always been one of the religious 3K oil changers with dino. With a 7qt fill capacity, I don't know if I'd see any real advantages going to synth? The engine is already going to be running cooler with either due to the large volume of oil... The only thing I can see that I would get would be better cold weather starts and extended drain intervals. Can anyone make any other arguments why I should go synth?

The information you are getting from your mechanic is basically 30+ years old. I'm not bashing old mechanics but some just don't keep up with the times. Alcan is of course one of many-many exceptions to the rule (he-he).
cmack4: If you go over to the Synthetic Oil board you will find a couple thousand of arguments for using (or not using) synthetic oil.

I've perused the board... not read every post, but a lot of them. The results are so mixed that it seems hard to get a straight answer. My question to you would be, what advantage would I really see using synthetic for say 5K miles versus dino for 3K? Obviously, I'd get better cold weather starts. What else? Will the 7 quart fill cap. effect the performance of either?
Mar 10, 2002 (7:44 am)
I feel fortunate that I do not yet own a vehicle that is prepared electronically to tell me when to change oil! I know my time is coming for that, and it appears unavoidable. I suspect that I will elect to not "get with the program" and will change oil and filter far more often than is really necessary, just as I do now. Many thou miles down the road, the "light believers" will try to wave me down to help them, as I sail by at speed in my over maintained rig, and they broil on the shoulder of the road. (:oř
