Yes but I do not wait for it to get to 0%. My last oil change I believe I changed it at around 35% which equated to about 7k miles. I do a lot of highway driving and don't feel like I am doing any harm to the engine by stretching it out that far. I am currently at 30% now and plan to change this weekend. Running the Motorcraft 5w50.

 

I use the OLM. It measures a variety of variables beyond simply mileage, so I'm going to go by that rather than just the odometer. I don't typically let it go all the way down to 0%, though, because sometimes I'll get a good oil change coupon in the mail from the Ford dealer, so it might get it changed when the OLM still says 20%. Or if I'm ready to put it away for the winter I'll change it, even though there's quite a bit of life left.

 

You people who are changing the oil at 5,000 miles are just wasting money for nothing. I run Pennzoil Ultra and change at about 9,800 miles. I've sent the old oil in to Blackstone for testing and they came back and said it was good for another 7,000 miles. Now, I wouldn't recommend a 17,000 oil change interval, but clearly 10,000 miles is well within the safe limits and at just 5,000 miles the oil is barely used.

 

I strictly use the OLM and change it at around 15% resetting it to 100% afterwards. 8.5 quarts of Mobil 5W50 Full Synthetic and a Napa Gold oil filter. Not sure exactly how many miles that equates to but im positive its well over 5k.

 

With the GT it's more of a time thing. I don't like to leave the oil for more then 6m on a car that sits ALOT, that's not good. The Raptor not only does 90% of the DD duties, but also tows the GT a decent amount of the time. I figure for $40 more a year it's cheap insurance and good piece of mind.

 

YES. I always check it when I get home to see where it shows on the dipstick. I have no oil drips on my garage floor, so I guess it simply "used" the oil that's apparently gone missing since it was changed. I've heard these engines are notorious for using a bit of oil. I check it fairly often, but I'm sure I haven't wiped that much off the dipstick. Thanks for the reply.

 

That's your case, but most Mustangs are daily drivers. Same with racing, if you're racing it then sure, change the oil more frequently, but for the normal average person who buys a Mustang and use it as their only vehicle, the Ford recommended 10,000 mile interval with their synthetic blend oil is perfectly safe. If you switch to a fully synthetic oil, even better.

At 5,000 miles the oil hasn't degraded enough to make any difference by changing it. May as well change it at 500 miles if you just want to have the placebo effect of knowing the oil is always perfect.

 

I think I'm gonna start changing my oil every 500 miles. That way it keeps nice and clean. Ba ha ha ha. Haven't used my Oil Life Indicator system yet but I probably should have. I go around 7500 k between oil changes and still have 40% oil life left.

 

Weird, my '13 V6 showed 35% left after 2000km, that's ~1250 miles. At first I thought it meant 35% used... I don't drive it hard. So no, I won't be using the OLM unless it smartens up!

 

You go 7,500,000 miles between oil changes????

Ok sorry, bad joke. Engineering side of me coming out.

 

I agree with Moustang but in my case I like changing it every 5000 so I can have them rotate the tires for me.

 

7,500,000 but I change the filter in between. Lmao. That's real good motor oil I use.

 

By the monitor. Ford added an additional quart to the oil pan to extend the oil change interval. And with the great synthetics we have available today, no need for early "old school" oil changes.

54K on its odometer, and running strong.

 

I'm at almost 18k miles on the odometer and 7k miles on the current oil. I checked it for the first time the other day since the last change and was at about halfway on the dipstick. Very happy to know it does not consume much oil at all. I had a beater car a few years ago that would burn up a quart every 1,500 miles!

 

If im doing alot of driving around town ill try to change it every 3-5k. If its sittin for a lil longer sometimes ill wait for 6k to change. But shes got 35k on her now so oil change comin up!

 

I use the monitor, and 5W20 Mobil 1.

 

I haven't heard of any ford motors getting screwed up by following the OLM. When my friend worked for the chevy dealer those engines 3.6L would need new timing chains. I basically go 5-6k before changing my oil.

 

I'll go against the grain here.My first vehicle with a monitor was an Avalanche. I started using the monitor with that vehicle.I have been using full synthetic for many years and have several friends who are Amsoil dealers, another who is an engineer with Mobil and know an individual who works with maintenance at Schneider trucking.
Changing your oil on a short periodicity is not wrong, but you're probably wasting money. Major trucking firms like Schneider change the oil every 100k miles. Most vehicles recommend longer miles between changes since engines are built so much better and fuel injection reduces the amount of fuel contamination in the oil. The Amsoil guys recommend taking oils samples and replacing the oil when the sample indicates riding contaminants. They do replace filter when reaching the recommended mileage. My old 97 Taurus was msintained this way and has over 150k and burns no oil and has had no valve or cylinder issues.

 

My mother has a 2004 Toyota Hylander and is equipped with a oil life monitor system. The oil gets changed only when the oil monitor system reads time for an oil change. The car doesn't get changed at any particular set mileage but only when the oil light goes on. It has 230,000 plus miles and running strong. Take that for what ever its worth.

Certainly its not wrong to change your oil at 3000 miles. Heck, change the oil every 1000 miles if anyone likes. Its your money. It's a waste of perfectly good motor oil but rock out. Its your vehicle do what ever you want. Change the oil at 500 mile intervals if that's what floats ones boat.

I would say our oil life monitor system is a great tool and fine too use for accurate oil change intervals.

 

First oil change will be at 5000, then twice a year as it is not a daily driver. If and when it becomes a DD I'll follow the OLM.
