I've found a rust free 450SEL and I'm curious if the car will run on mid-grade gas. Also, what mileage can I expect on the road? Tom, Nitske's page on the 450SEL cover 72-80 model years so his fuel consumption figure of 16 MPG is pretty general. Given that the 72-78 had a 3.07 rear gear, the 79 had 3.06(?), and the 80 had 2.65:1. Your 77 would have a performance gear and I would suspect 16 would be hard to average pulling around 4100 pounds. The fuel is specified as US: no lead fuel with no mention of octane, which implies low octane is OK. The 6.9 page, for example, calls for "super" in the fuel category. US horsepower for the 77 is quoted at an anemic 180 (@4750 rpm) with a compression ration of 8.0:1, which should be very happy on the cheapest blends. Fuel tank capacity was 25.4 gallons. Some other specs: 0-60 in 10.8 seconds with a top speed of 127 MPH. the 77 sold new for $24,506 (east cost POE). Of the 59,575 sold in the USA, 10,042 were labeled 77s. If you buy the car, I would be glad to scan the two pages for your files. Regards, Jim Friesen Phoenix AZ 79 300SD, 261 K miles 98 ML 320, 137 K miles
