The initial oil changes are very important imo. Get a few hours on it and change the oil. They probably recommend 20 to 25 hours at least for the first change. Small engines often recommended 25 hours depending on the application. My Honda is every 100 hr but I changed it at about 2 then 8 or so then 40 and then keep it under 100. You will probably see a swirled almost metallic look to the oil at first. This is important. If you are running it under heavy load high heat conditions all the time then tend to change the oil sooner. Oil is cheap. Edit: I went out and checked my oil change record: 2, 6, 72, 146, 325, 446, 526, 604 Thank you. I also change my oil frequently also. I run my Honda 2000's 8-12 hours at a time at my camper. Always changed it every 40/60 hours. What's 13 ounces? Have over 3500 hours on each. Thanks againSpark plug gap questionI purchased the HF Predator 3500 generator yesterday. The manager is contacting the maker for me to clarify the oil change intervals. I will update. The manual recommends the plug gap to be .027"-.031". That's kind of a range here. Anybody comment on the best gap? The average would be .029". Which gap would you feel would be better at 2500 feet? Tech support is of no use. Thanks.Re: Blue genny guy did the unthinkable! MrWizard wrote: 8 hours sounds like the break in period, first run Run it 8 under medium load change oil Change it once every 6 months if it is just sitting in the garage and only run occasionally, did not get to 100 hours If being used in daily or weekly service, change oil every 100 hours Sounds like they forgot the descriptions that go with the chart The above could be considered fairly typical Actually according to the manual, the first 25 hours is the break in period. It says do not exceed 75% of rated output during this period and then change oil. I'll err on the safe side and change earlier. It's only 20 ozs of oil. Definitely will get one of those magnetized dip sticks. I have them for my two Honda 2000i generators and when changing the oil there's always a little black residue on the tip. Those two Hondas have over 3500 hours each. I change the oil at 40-60 hours.Re: Blue genny guy did the unthinkable! benevolus2 wrote: There's something in the maintenance manual for the Predator 3500 that's confusing concerning oil changes. In the chart it says change oil monthly or 8 hours, then 6 months or 100 hours, and finally yearly or 300 hours. So which is it? Here's a good one for you. I just call 'technical support' at the number listed in the Predator manual. I asked the 'tech' about the oil change interval. At first he said you understand these manuals are scripted in China by people with sometimes limited command of English. Told him the chart is ambiguous. He responded that's it's very clear. If you use the generator eight hours, change oil. If you don't use it much then you can wait! The guy really didn't know squat. Bottom line, he said change oil EVERY eight hours period. Wow.Re: Blue genny guy did the unthinkable!There's something in the maintenance manual for the Predator 3500 that's confusing concerning oil changes.

Excellent point and answer to my question. Thank you.Re: Water tank question GordonThree wrote: What do you mean filling the tank but not blowing out the lines? I've always blown after the tank was empty. Water in the tank is also water in the strainer and pump head. These are the weak spots for freeze damage. Maybe leave a 60 watt bulb on next to the pump and strainer? Right tank is empty and lines are filled with antifreeze. Without blowing out lines just wanted to know if I half filled tank, could it get damaged from possible hard freeze. As for leaving bulb on, no power when I'm not there. ThanksWater tank questionI keep my 2004 Coachman TT boondocked on my land located in upstate New York with no services. I'm pretty sure there's not going to be long term hard freeze at this point. However, I'm always like to err on the safe side. My question is, I was considering filling up my water tank half way in preparation for de-winterizing, but not blowing out the lines at this point. If there was a hard freeze could my tank get damaged? Thanking you in advance for your input.Re: To tape or not to tape Almot wrote: People saying to tape flared, don't understand how flared fitting works. Like Cloud Dancer said, tape or sealant would make things worse. I didn't understand either till I learned here. Never noticed that little seal on the female side! So only on tapered or straight threads.Re: To tape or not to tapeWell, the verdict is in : no tape. Thanks to all for your answers and expertise.
