My regal 4 months old with 301x miles on it, according to the dash computer, i still haven 45% oil life remained ...
So should i stick to the 3m|3k or wait until the dash computer tell me to change oil now?
btw, anyone knows regal uses regular or synthetic?
This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed. When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on.
Change the oil as soon as possible within the next 1 000 km (600 miles). It is possible that, if driving under the best conditions, the oil life system might not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer has trained service people who will perform this work using genuine parts and reset the system. It is also important to check the oil regularly and keep it at the proper level. If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 miles) since the last oil change. Remember to reset the oil life system whenever the oil is changed.

havent looked yet, but where is the filter hiddenfirst oil change at 15000, 6 months after purchase. Almost all highway miles. Mobile 1 now sports the dexos 1 certification. changed the oil myself. piece of cake once you figure out where they hid the filter. do yourself a favor and pick up the special filter wrench at your local autozone or amazon.com

Is there a non synthetic with the dexos approval? I haven't seen any yet, doesn't mean there isn't. Just saying I haven't seen it.Still trying to figure out if the Regal came from the factory with Synthetic or not. Contacted the dealership where purchased and they could not confirm. Sent an e-mail to Buick to find out for sure. If anyone knows for certain, please share. If it came with synthetic, definitely want to stay with it.
