Default 5000 miles vs 7500 miles

Just bought a 2010 2.5L Fusion. Was reading through the manual and saw the OCI is 7500 miles, where as previously it had been 5000. Something about this makes me uncomfortable considering the Motorcraft oil isn't full synthetic.

What is your opinion on this? I'm really tempted to stick to the previous OCI.

I believe all 09 models have 7500 oil changes as well. I was worried like you so I asked my tech guys at the dealership and they said 7,500 is ok but if you want stick to 5,000 mile intervals. Really it does not matter. The car can go 7,500 and the BMW Z4 has 15,000 mile intervals. I do oil changes every 6 months at about 6,000 miles.

Hi Marshalus. I agree with roaf. With modern engine and oil technologies, a 6 month/7,500 Normal Service OCI is perfectly acceptable. That goes for Conventional, Synthetic Blend or Full Synthetic oils. Otherwise, Ford would not recommend it.

In fact, the first Ford US passenger car to adopt the 7,500 Normal Service OCI was the 2007 model year MKZ, when the new 3.5L engine was introduced. With the 2008 model year, the rest of the Ford lineup/engines adopted the 7,500 mile OCI.

If you are not comfortable with 7,500 mile OCI's, use the Severe Service OCI which is 6 months/5,000 miles. In the end, it is all a matter of personal preference. So use any OCI (up to 6 months/7,500 miles) you feel comfortable with. There are even some people who still use the old 3 month/3,000 mile OCI.

Bottom line is that considering the average annual mileage driven by US drivers, many drivers will need to change on the time interval (6 months) before they ever hit the 7,500 mile mark anyway.

I also agree with biggee. :lmao:

Whatever you decide to do, good luck.

Yeah yeah, I know this probably something that got debated a lot when they made the change. I'm new around here

I also come from the VW world where if you didn't maintain a 5K OCI with VW 502.00 certified fully synthetic oil the VW gods would come down and beat you... or just sludge up your engine. This was after their original owners manuals for years said use whatever you want as long as its 5W-30 and they were forced to revise it, and after they spec'd out an oil filter that was two sizes two small and had to reissue guidelines years later to use a larger one. This was after putting a 4qt reservoir on a turbo charged car.

I guess I'm just paranoid about these things.

Of course you agree with me because I am taking the words right out of your mouth from the last time I asked this question. If anything I should have gave credit to you.

Personally as I live in Canada and have an extremely short commute to work (3km one way) I follow the "Severe Service" intervals (6m / 8,000km) and even then I've decided to eat the cost of full synthetic oil.

I have no idea what the conditions are like that you drive in and I believe that should also play a factor as to whether you do the barest minimum as per the manual or that bit extra for a car that you own (A leased car throws the equation for a bit of a loop)

Default Re: 5000 miles vs 7500 miles

I "grew up" on the 3 month/3000 mile OCI. As I became older and got a job with a 38 mile commute, I researched this and realized that even on my 01 Pontiac Sunfire could go with a 5000 mi OCI.

So...when I bought my 09 Fusion, it came with a 2 yr/25000 mi Premium Maintenance Plan and I am currently following a 5k OCI. However, I will gladly follow the normal OCI of 7500 miles once it ends. This happily works out well, since I have put 13,200 miles on my car since 3/4/09. I'd be getting an oil change every 5 weeks if I followed a 3k OCI.

Here's the bottom line, as I see it with regard to OCI: The engineers AND the accountants get together to develop the correct OCI. The engineers KNOW the engine and drivetrain, I don't--they are paid well to do so. The accountants want to minimize warranty claims. So...Ford will only put the recommended OCI in the manual that it knows it can back up.

It's your choice, but I see no reason not to follow a 7500 OCI as long as you don't meet the Severe Service Schedule.

They also don't want to take too big of slice out of service revenue for dealers....
