2006 Buick Lucerne 3.8L V6 (GM 3800 series III)
123,000 miles
Manual recommends 5W-30.
Location: North Carolina
I bought this vehicle recently and haven't changed the oil in it yet. Being that it sees frequent, repeated acceleration followed by idling when I deliver mail, I figure I need a better than average quality oil. Transmission will get Amsoil and Lubegard, but I'm undecided on what motor oil to use.
Previous vehicle was a BMW E38 and I used Castrol Edge Titanium or Pennzoil Platinum Euro 5W-40.
On the BITOG forums I've seen a lot of comments stating that thr 3800 engine doesn't care what oil it gets. I understand it's not as important as for some motors, but this is my work vehicle and I want to get as many miles out of it as I can. It doesn't have any leaks and hasn't burned an appreciable amount of oil over the past 5,000 miles. I prefer synthetic, though I'm not sure I need high mileage formulations given that it has no issues and no leaks. I'm more looking for a durable oil, not performance or efficiency. I would just call it a day and put Amsoil in it but I put a lot of miles on this car and I can't argue with the price of Pennzoil or Castrol at Walmart.
Additive recommendations are welcome too. I used to use Liqui Moly Ceratec in my 740il.
