Engine Mechanical problem
1999 Cadillac Deville V8 Front Wheel Drive Automatic 118657 miles
I was just wondering, what type of oil do most of you Northstar Caddy folks use?
Its time for me to do my first 3000 mile oil change since I bought my Caddy, and it says on the windshield sticker, it was last changed with a brand called "Northland" motor oil. I've never heard of that brand, and can't find it on the internet.
Over my many years of driving, I've used Trop Artic, Valvoline, and Havoline with really good luck.
I had problems with Penzoil in a old 65 Ford, it looked dirty even when it was new, and when the engine blew, I chalked it up to that Penzoil. Who knows though, I was a Hotrodder back then.
I heard this Purple Synthetic oil helps one get better Gas Milage, but I'm already getting 28mpg on the highway, and around 22 to 24 around town, depending on weather or not I'm using the AC.
Just thought I'd ask your advice. I'll probally go with Valvoline.
