When the filter clogs, you may be walking. Do you know how many miles ago it was last changed? You have to remember, that tank has had many gallons of gas run through it, sat and had condensate accumulate on the interior of the tank, which causes rust, which flakes off into the gas, which ends up in the fuel filter. Filter 5-6 buck, good investment.
Oil turning dark would be normal, inside of engine has heated a lot of oil over many years, had oil cook in spot and stick, even turn to sludge. How many miles do you drive it, under what conditions, before you have to add a guart?
