It's sort of a returns calculation - the cost of repairs, versus the future life of vehicle versus car payments. When Nessie had major repairs last year - the guys we really trusted (not above) told us the engine was in excellent shape, as is the chassis - and that really it was worth it to do the maintenane. Which ended up being about $500 (a weird thing that happens in these- it threw a spark plug - has to do with the alloy in the engine, etc and we were lucky there is a specialist that could drill out the old one and rebore with an insert the cylinder so that a new spark plug could go in). Then, in the fall, new alternator which led to new starter, and we just needed tires.
Yes, we have the Eddie Bauer with the big tow package, so it's the biggest engine. The trusted mechanics told us to put in the higher octane - it makes a difference with that big engine and the mass of the truck. So, we started doing it and it's definitely in the plus column of mileage versus gas. Right away - city driving went from 14 to 17-18 mpg. So now I generally use 91 or 93, but sometimes 89.
True. Traffic is so bad around here, and dangerous, that I'm hesitant to go that small - though we do drive the TT which is little - but has a great safety record and airbags. One of our friends has a mini-Cooper - and she's very tall - about 5'11", and her sister is over 6' - so it's hysterical how they unfold from the mini Cooper.
Things happen!
