Oh, a LOT, I assure you!
But that 5.7, while thirsty, is about bulletproof, from what I’ve read and experienced.
In 9 years and 85,000+ miles - I’ve done brakes, tires, and oil changes.
That’s it.
Yeah, it’s thirsty, when pulling a trailer with a car on it - I get 10 on the highway. Unladen, I am lucky to get 17. On the highway. About 14 around town. But I knew that when I bought it. I chose reliability over efficiency.
Fuel is a predictable expense. Major repair is not. And a breakdown when far away from home is a huge pain. I didn’t want twin turbos, a water pump inside the block, variable cylinder management, or any of the other MPG tricks that added complexity.
