I own a 1988 Ford Escort with 506K+ miles still running on the original 1.9L engine (never rebuilt) and 4 speed manual transmission. It currently uses a quart of oil about every 1000-1200 miles. This just goes to show you that with proper maintenance a car will last for many miles/years. I've been using 10w40 conventional oil in it most of it's life, with oil change intervals probably averaging 4-5K miles and currently I'm using Lube Control LC-20 and letting the oil change interval go for their recommended oil change interval of 10K miles. I've been doing this for the last 31K miles and so far haven't seen any negative effects, such as increased oil consumption from the long OCI. Just in the past few days I've found out that some of the members over at www.cleanmpg.com have been contacting Ford Motor Company about this car trying to persuade them to give me a new Ford Fiesta for it. I would also appreciate anyones help on this forum in contacting Ford. Maybe if they receive lots of comments on this car it will get their curiosity up. I think it would be good advertising for Ford, plus good for customer relations.
