Ok question. Had my bike in for its first, 1000 mile, service (09 1200c Sportster) and they tell me it is due back in 1500 miles. However my 09 owners manual states it is not due back until the 5000 mile mark. So which is it suppose the be? I had then use the full synthenic oil when they changed it. Is the dealer trying to pull a fast one on me???
Thanks
Oil change intervals in the owners' manual are guidelines. Many HD owners ask that the original "Break-in" oil be changed out as early as 100 miles, then 1000 miles and then every 3000 to 5000 miles after that, depending on how hard you ride your oil based on the following:
1) Do not ride 30 mins or longer to fully get the oil up to temperature (evaporates condensation that causes sludge).
2) Idle engine continuously for 10-15 minutes idling stopped or lug the engine in too high a gear and go rarely up to 55 mph or more, again for less than 30 minutes or longer.
3) Run in high humidity or high temperatures for long periods of time.
All these conditions age an oils, (though full synthetics tolerate this abuse better) so it is possible even a 1500 mile oil change could be a good thing. Rate your riding over verses the above conditions.
Of course, many of us at HDT do our own maintenance, using full Synthetic 20W/50 in the Engine and 85W Gear Oil (non-Syn) due to better clutch performance w/Gear lube for combined tranny/chain case in your "2 fill hole" Sporty.
Since we do not know if you have extended service/warranty benefits with your servicer, we cannot advise you as to whether you should take up their offer. Personally, if you trust them, and they do good work, by all means continue...but later on, I would consider getting the Service Manual and doing it yourself, there are plenty of ways to save money, yet support your local dealer(s) while having enough left over to improve your riding gear or add performance and bling to your ride!
