Check the survey. Somebody had posted a link to it...I simply use 10w-40w, any brand. It only stays in the engine for 5000 miles or one season. Then it goes into my Ford Expedition for a while before I take it recycling.
skip.
I've been using diesel engine oil. It's super heavy duty and has many of the additives that have been removed from normal gas engine oil. This year, I am trying Mobil 1 5W40 A little thinner when cold to help with flow, then 40W when hot. So far so good. I do run a filter, don't drive the car more than 1000 / year so I only change it in the spring.
And the 2011 Mustangs I've been looking at as well as ALL of the 2011 Ford Motor Co. line-up,,,Ford recommends 10,000 mile oil change intervals!!
Man, it sure has come a long way---
I'm sure some cheap skate tried that back in 'the day' wonder how long those engines lasted on that nasty 1930 era oil?
hey, i had an uncle that tried that with every car he owned. He didn't believe in maintenance. He'd just drive until the oil light came on, then keep driving until he came to a place where he could buy another quart of oil to dump in. His daughter's husband is the same way. He just destroyed an engine a few weeks ago, now my cousin needs to find another car. I never could figure out why some people think an engine or car is cheaper than an oil change.
Tom there is farmer close by that does this exact same thing. He always buys a new Mercury, runs it 60,000 miles to the end of the powertrain warranty with NO oil or filter change, then runs it back to the dealership and trades for a new one.
Everybody knows it so nobody around here will buy a car from him. The dealer just drives them to St. Louis to the big car auction and unloads it.
I'd sure hate to be the guy that bought one of those cars. And this guy is very very wealthy it's not like he can't afford an oil change. He will drive to Macomb (about 60 miles) if they are offering a free pork chop sandwich at some seed corn expo, he does this all the time!! It's just the idea of 'free'!!!!
10,000 miles a season, Shell Rotella 15W-40, changed every 500 miles.
I've been hearing that the zinc is being removed or eliminated in even the "diesel" oils. But I cannot find anything definitive on this. Anyone?
