czakky Posted September 1, 2015 Share Posted September 1, 2015 Sorry to post a dead horse topic here but I'm just still baffled by something. My normal oil level check routine is either A: In garage before starting check oil level while on bike mostly horizontal to the world, dipstick screwed in all the way. Or B: same as before only after I fueled up and bike is warm and been sitting for 60-90 sec. On Sunday I used method "A" before heading out and was surprised to see I was 2/3 low between marks. Topped up a half quart of Mobil 1 and off I went a little perplexed that I had gone through so much oil in only 1k miles. After scaring all the dairy cows I could find in SW Wisconsin I was on my way home and decided to check my level again (method "B") now I was at least a half quart over the full mark....? I know oil expands and there is bound to be some oil that hides out in the thermostatically controlled oil cooler. I usually don't have such a variance between hot and cold readings. What is happening? Should I lose the extra half qt.? Link to comment Share on other sites More sharing options...
grossohc Posted September 1, 2015 Share Posted September 1, 2015 I have only ever measured the oil level with the bike cold and level, with the dipstick just screwed in. Link to comment Share on other sites More sharing options...
LowRyter Posted September 1, 2015 Share Posted September 1, 2015 I measure mine when it's cold. When it's hot it's possible that the oil is draining down from the top end and getting all over the dipstick and showing the oil level to give a false overfilled reading. On the other hand, the oil is still draining down and if the dipstick isn't in the down flow then the level reads falsely low. He have come to a consensus here that an accurate level can be observed whether the bike is level or on the side stand. I would think it's better to check it when it's cold and the oil has drained to the bottom of the sump. Link to comment Share on other sites More sharing options...
czakky Posted September 1, 2015 Author Share Posted September 1, 2015 Ok, i thought I remembered the manual saying the level should be checked after running but I figure that is usually for after an oil change. I will stick to my usual method and try to find out who keeps stealing the oil out of my bike.... Link to comment Share on other sites More sharing options...
JRD Posted September 1, 2015 Share Posted September 1, 2015 Those 8,000 RPM power shifts probably don't help! Link to comment Share on other sites More sharing options...

docc Posted September 1, 2015 Share Posted September 1, 2015 By "mostly horizontal" you don't mean lying on its side? Link to comment Share on other sites More sharing options...
fotoguzzi Posted September 1, 2015 Share Posted September 1, 2015 That's one of the things I like about Guzzi.. My Buell requires oil check when hot, as in w/in minutes of shutting off. It's a real bother but if I wait till it's cold it doesn't even show on the dip stick, I've added to much more than once. Link to comment Share on other sites More sharing options...
czakky Posted September 2, 2015 Author Share Posted September 2, 2015 @Docc geometry was never my strong suit... @Foto I think I had a Kawi like that too. How does that even work? Dry vs Wet sump thing? Doesn't make sense to me.... Link to comment Share on other sites More sharing options...
Craig Posted September 2, 2015 Share Posted September 2, 2015 Isn't that what the oil level warning light is for? Link to comment Share on other sites More sharing options...
Kiwi_Roy Posted September 3, 2015 Share Posted September 3, 2015 What oil level warning light, my guzzis only have a pressure switch that comes on when it's too late like out of oil. On that note the switches are very unreliable, my V11 Sport and the Eldorado now have pressure gauges. Link to comment Share on other sites More sharing options...
Don G Posted September 3, 2015 Share Posted September 3, 2015 I never bother to check the level in any of my Guzzi,s between changes, what for? DonG Link to comment Share on other sites More sharing options...

Yes, that is how semi-dry sump (separate oil tank) systems have to be checked. And, yes, it's a PITA. Link to comment Share on other sites More sharing options...
Gio Posted September 7, 2015 Share Posted September 7, 2015 I would recommend the cold and level method - this has always worked for me. Alternatives - although viable, introduce variability (how warm is warm, how consistently not level ... etc) Gravity is your friend in this matter!

moto fugazzi Posted September 7, 2015 Share Posted September 7, 2015 You were in SW WI? Only a few hours from me. Wish I would have known... Ken Link to comment Share on other sites More sharing options...
