I have always taken my cars in to have any maintenance done....until I bought the Stangs ......now no one touches 'em. My question is, the 95 Cobra with 152,600 miles ( bought it at 150 and changed the oil 1st thing ) needed a quart, Is this something to be concerned about or is it normal for a high mileage car. None of my previous cars needed oil before the 3k change including a 91 Escort with 200k.

 

In theory if you have to add oil between regular changes its leaking somewhere or burning, although its not uncommon to need to add oil in a high-mileage engine.

 

High mileage engines use oil. As the engine ages, the pistons and rings can start to go "elliptical", i.e. slightly oval with wear, a little oil gets past this minute gap and burns with the petrol. I do not think it is anything major, just as long as you are not driving down the road trailing smoke. An engine rebuild would sort it as the pistons and rings would probably get changed

 

i have a 95 gt and it uses very little oil w/ 135k miles but my friends 04 gt burns almost 3/4 quarts of oil by the time of the next oil change, both stangs run beautifully, they just happen to use oil, quite normal

 

Great....Thanks for the help. It may not have actually gone through a whole quart as it was at the low end of normal at the oil change and is now at the high end after adding a quart (It had gone below normal before I added, but just barely) .

 

Saturns burn oil because of the engine design...

 

If you only burn a quarts every 3k miles, then you have a perfectly normal used 302.
