rockfangd Posted September 23, 2019 Report Share Posted September 23, 2019 My spiritedly driven 97 Deville at its finest. How many people can get 20 mpg out of a 23 year old v8. Even better is that I do not recall adding any oil (Oil life at 2%) What a wonderful ride.

sprucegoose Posted September 24, 2019 Report Share Posted September 24, 2019 That is pretty cool, a good feeling for sure! 👏🏻 Especially like you said, with that kind of mpg for a V8! My CTS with a V6 barely squeaks the 21mpg mark. I never let my oil life monitor get that far down though. 30% is my limit with timing chain wear concern. That’s incredible oil use for a Northstar, I’d say you got one that rolled off the line on a Tues. through Thursday! 😆 rockfangd 1 Quote '09 Cadillac CTS-4 3.6 direct injection, 128 K mi.
