The brand of oil isn't the issue, it's the type of oil that makes it ';better';. Conventional oil(petroleum based), Semi-synthetic(petroleum/man made blend) and full Synthetic(no petroleum used) are what's on the market today. If you change your oil %26amp; filter regularly, conventional oil is fine(after all it's been around since the advent of the automobile). Your Buick's V-6 is an OHV design and rarely sees over 5500 RPMs, so investing in semi-synthetic or full synthetic is fine for peace of mind, but isn't really necessary(IMO). Go with what GM recommends, all the major brands you've mentioned will be just fine.
This subject comes up all the time and everyone seems to have


a different answer so it's one of those battle answers.





Unless you've been using synthetic from day one. Buy what's on


sale and keep your oil changed on a schedule. Don't overdo it, and


don't leave gaps. Engine conditions and driving habits are going to


effect the engine a lot more than wondering which brand of oil to use.





I buy what's on sale, change my oil on a regular schedule, just pulled


the valve covers to do a gasket, and everything is as clean as a whistle. Use a name brand filter and you are ready to roll......
No, there really isn't a better oil than any other. It all depends how much you want to spend. The important thing to remember is to check for the type of oil your vehicle's maker suggests to use. SG, SH, etc. can make a world of difference for your engine.





Also, it depends on your climate that the vehicle is exposed to. This is where W5, W20 and such come into play. Your vehicle's manual has a chart on this as well. Take a look at it and you will be amazed.
Absolutely not. If you change the oil as recommended, they're all more than adequate.
i swear by Castrol.
