everyone says to much oil is worse then running a little low on oil....why is a little to much oil not good?
Take your hand and swing it through the air, now go to the tub and run it full of water and then swing your hand through it. Thats the effect of the motor running with oil hitting the crankshaft. Over the years I have seen several engines come in running terrible with too much oil in them. Some to the point they were pushing oil out all the seals. However I have never seen it do any long term damage. Every time I have been able to drain out the excess and all returns to normal. The engines have no power at all though because of the slapping the oil that takes place with the crankshaft, many won't even idle right with them overfull. I don't consider it nearly as bad as running an engine low on oil though.nval8 said:everyone says to much oil is worse then running a little low on oil....why is a little to much oil not good?
Your right it will foam, and thats why it pushes it out the seals from pressure. Usually when they have oil hitting the crank they won't run fast enough or hard enough though to get the power to damage them from the foaming of the oil, or I will say I haven't seen them. They run so bad you have to know there is something terrible wrong with them right away.Pondo said:I thought it was an issue of beating the oil to a froth, getting air into it, and then the oil not lubing right and focking up your engine.
Have you ever driven a car or ridden a bike that the oil is hitting the crankshaft? If just driving the oil pump takes 7hp in a v-rod can you imagine how much hp you give up when the crank hits solid oil every time it passes?jlavallee said:As a ICML certified machinery lubricant analyst (worked as a maintenance engineer for a few years) I can tell you that the main thing you're worried about is in fact foaming of the oil. Yes, there are anti-foaming additives in the oil but if you excessively overfill and create a foaming condition you will have metal-metal contact.
Of course, the pressure created in the base can possibly (depending on design) blow seals, pump oil into the breather tube possibly washing into your filter or down the intake etc. But it is the foaming that matters most.
I heard through the grapevine that some one might be working on a new pump that has the same pressure but uses only 4hp. But you know how rumors are.Steppenwolf said:really?! Holy crap - I had no idea it was that much.
