4-5K, Mobil 1 15-50 syn car oil

 

I stick to 5k using synthetic oil, seems fine to me.

 

I agree with the 5K engine oil as the manual says. Also, primary oil is every 10K and transmission oil is every 20K. Why waste the 2 quarts on the tranny and primary if you dont need to.

 

5,000 miles for all the harleys i've owned as well as my 08 sg. no problems yet, and with running full synthetic i still do it at 5k miles.

 

I change mine when the oil light comes on. I use Walmart brand car oil...seems to work good enough.

Isn't that what the oil light is there for....c'mon guys...think a little....trust your oil light!

 

I think that sae 30 oil for the lawn mower is a little cheaper, might want to go with that next time.

 

I believe you are right...forgot about those little bottles...thanks for the heads up!

 

Average 525 miles a week going to/from work daily on my 2007 Ultra. I follow the service manual at 5000 for engine oil and longer for tranny/primary.

However, I keep an eye on the oil and if it looks too dirty, will change it earlier.

Dealerships love to tell you every 2500 miles, I would too if I could sell you an oil change for $300+ dollars!

I buy oil based on price and use. Summer I run HD Dino straight 60 wt. Usually run whatever the cheapest motorcycle Dino 20-50 wt. is the rest of the time.

I do buy the premium filters though.

 

Use synthetic and change every 5k miles. Most of my miles are highway. If I did a lot of city riding, I'd probably change a little more often.

 

5K here. Amsoil all three holes.
