Wow, I was looking on Buicks Website, 7500 mile oil change is recommended for my GS..
I know you have the 6 and not the turbo 4, but with the full synthetic Dexos oil even the turbo 4 safe interval is 7,500. In fact, that's exactly where my oil life monitor pinged.
I know many higher end European cars have oil change intervals at 25,000 km,.. and that's because the oil pan on those cars holds 10.5 quarts and to change the oil you have to drop the oil pan because there are 2 oil filters inside the pan.
You are aware that should you have a engine related warranty issue and you have not changed the oil at the recommended mileage or time, they may give you a hard time or deny coverage.My GS is telling me I have 5% oil life left after just ~1250 miles and about 13 months. I'm getting annoying calls from the dealer and from onstar about it.
Correct. GM has had me call customers and have them provide proof of oil changes if you're not on record at any dealer in the nation with having oil changes done. All GM service centers are linked to GM Global Connect, and all service performed at a GM facility is on record and can be seen by any service adviser who is checking you in.You are aware that should you have a engine related warranty issue and you have not changed the oil at the recommended mileage or time, they may give you a hard time or deny coverage.
Buick lets you decide when you want the 2 free changes, did my first one before 2000 miles.Yes, I understand about the whole warranty issue, Merc wanted an average of $1,500 a year for mandatory maintenance (the "A" & "B" maintenance) which is why I don't own my C300 any more, I have nowhere to change the oil myself right now, so I have to get it changed by someone. Just happens that the dealer gave me 2 free changes when I bought the car. But 12 months before oil gets to gunked up to be safe? Give me a break. Unless the car business has really gotten deep into the planned obsolescence bullshit.
Yea, I did my 1st around 1,000 miles and paid the difference for Mobil1.......even though our bulk dexos license oil supplied by GM comes from EXXON/Mobil. I just wanted to spend money i guess. That must be the reason since I just did my 5th oil change and I'm at 11000 miles. Most folks say I waste my money changing oil every 3000 miles, but I like the feeling of having clean oil more regularly in my engine. I certainly don't recommend that to my customers when they ask how often they should change their oil, but I prefer it that way for my car. Every now and then I come across a fellow money waster who likes to change their oil more frequently. In fact, its more common for folks to wait until 0% oil life before changing their oil. I personally could never do that with my car.Buick lets you decide when you want the 2 free changes, did my first one before 2000 miles.
