Default New vs Old

My friend has an 89 Wide Glide and we got into a discussion about oil changes. He said I should change the oil at least every 2500 miles on my 07 S B. I disagreed with him and told him the manual has it at every 5000 mile interval. His doesn't get rode anything like mine since he said he only changes it twice a year. Is there anything I'm missing in this picture? What's really funny is when I asked him how often he changes it in his truck and car? I had to keep from laughing when he said they only recommend every 5000 miles for his F-150 and Explore.

I can't help but think that when it comes to the engine the people who designed, built, then tested it would know how often it needs the oil changed. I'm gonna go with the MoCo on this one.

I run dino oil in my Shovel. The manual for the Shovel says every 2500 miles. This is mainly because everyone used dino oil in the old bikes and it needs changed more often.In my 2005 I use sythetic and it can be changed every 5000 miles. There is a big difference between old and new bikes.

The 2007 Fords are rated for 7500 miles between service on syn blend.

just my opinion..2500 miles is better... 5k is to long . oil is cheap and fast to change.

Oil threads and discussions, regardless of what they are about, will always generate disagreement - be it frequency of changes, brand of oil, type of oil, weight of oil, etc, etc, etc.

Evo engines utilize a filter that doesn't filter particles as small as a TC's filter does (I believe a filter for an Evo engine filter particles down to 35 microns and a TC filter goes down to 10 microns (or something like that)). It's not good to use a TC filter on an Evo motor as it makes the oil pump work way to hard. It may be that HD may have recommended more frequent oil changes for these motors due to this back in 89.

As an FYI - changing your oil too frequently is just as bad as not changing it often enough. I can't remember where I read the study but frequent oil changes did your engine as much damage as infrequent changes. I go with the manufacturers recommendations. Now this is just my opinion and we all know how good opinions are......and where they lead.

This is mentioned in an article by "Lee C. Bussey" called "Oil and the Modern Day Harley Davidson Motorcycle". I'm sure it can be found with a google search. This is easy reading, and lets you come to your own conclusions. It does provide a lot of data. It addresses often talked about issues like syn vs dyno, the urban legend of "bearing skate", etc.

first off.your bike looks freaking awesome.. but.how in the heck could changing oil to often be a bad thing ? i am all ears on this one. hey,i may learn something new.

and yea,as always...the dreaded oil thread always pops up. LOl ..where they lead is always interesting indeed.

with my scoot,i have rule of thumb..once in the spring,once mid summer. i ride about 6k a year...maybey more this year. just bought my HD oil today.. oh no,another debate.what brand and type and brand of oil ..

ENGINE OIL 2007 specs

NOTE: Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the requirements of Ford specification WSS-M2C930-A and the API Certification mark.

NOTE: Do not use supplemental engine oil additives, cleaners or other engine treatments. They are unnecessary and could lead to engine damage that is not covered by Ford warranty.

Ford also states that it should be changed every 5,000 miles for "normal" conditions and 3,000 miles for "severe" conditions. Severe conditions means dusty conditions, towing, using flex fuel, offroading, extended idling, several hot cold starts. So Severe sounds normal to me. Regardless of oil type or brand the #1 reason to change it are the byproducts of combustion, moisture, metallic dust and any other foreign matter contaminating the oil not so much the oil itself or it's additives breaking down. My suggestion : dump it sooner than later

Where did you get this from? I just checked my owners manual. It says 7500 milesnormal, 5000 severe. I just bought mine last week. I do agree with you, 7500 miles seems long, but the dealer said they are fine to go 7500 miles without service.
