Here are the latest results form my last oil change. It was Kendall GT-1 Synthetic Blend from a Firestone service center with a Firestone filter. only paid 12.99 plus tax ,I had a coupon. Not too shabby...Oil seems to be pretty good.
OIL TYPE & GRADE: BULK Kendall GT-1 Syn Blend 5W/30 from Firestone service center
OIL USE INTERVAL: 3,150 Miles
Buick Lucerne 2006 3.8L V-6
17,900 miles
Firestone Filter
3-09 to 07-09 oil in use..
OIL ADDED- 0 Qts.- but it did use about 1 qt. or a little less(29-30 ounces) in those 4 months, I did not want to add any to keep the sample pure.
:Engine wear was a little better in the latest sample from your Lucerne. Copper is still high but that's to be expected since bronze parts are machined differently than steel parts. Consequently, copper takes up to ~50,000 miles to settle down to averages. The oil's viscosity was normal. No gasoline, moisture
or any signs of anti-freeze were present. The TBN was 2.5, showing some active additive. 1.0 is too low a
reading. Try 4,000 miles.
Numbers on left are from previous UOA shell 5w-30 dino, numbers on right are the KENDALL GT-1 syn. blend.
