A Cold winter starts are the likely culprit. Engines require a significantly richer fuel/air mixture to start in cold weather. A high percentage of the fuel that's delivered from the injectors and vaporized into the air drawn into the engine condenses back into liquid on the cold internal engine components, including the valves, pistons, combustion chambers and cylinder walls. The extra fuel supplied for startup ensures that enough fuel remains vaporized to mix with the air and ignite from the spark. Remember, the engine can burn only fuel vapor, not liquid fuel. If everything goes according to plan, the engine fires up quickly on the richer fuel/air mixture, begins heating the internal engine parts and ultimately re-vaporizing the condensed fuel and burning it during the warm-up cycle. This is why an engine will flood so quickly in extremely cold weather if it doesn't start in the first few seconds of cranking. In that scenario, the injectors continue to deliver fuel and more and more of it condenses in the combustion chamber, wetting and ultimately "drowning" the spark plug, making it incapable of firing. The result is a flooded engine. In some cases, holding full throttle to "unflood" the engine by maximizing air flow and reducing fuel flow will allow the engine to start. When the engine management computer recognizes a wide-open throttle at cranking rpm, it cuts the injector pulse width in half to reduce fuel flow to help clear a flooded condition. In your Celebrity, it would seem that at least some liquid fuel generated on cold starts is ending up in the crankcase mixed with the oil. A small amount isn't harmful, and in most cases will evaporate during a fully warmed-up drive -- perhaps 20 minutes. The danger, of course, is that gasoline is an effective solvent, diluting the oil and reducing lubrication to sensitive engine parts. You should carefully check the components and function of the positive crankcase ventilation (PCV) system to determine if it's functioning properly. It should draw combustion gases and pressure out of the crankcase and through the induction system. If the PCV valve or system is not working correctly, excess combustion blow-by, including raw fuel from a cold start, can end up in the crankcase. An iced-up PCV valve, leaking or plugged hose or filter can effectively disable the PCV system, resulting in excess crankcase pressure. A fuel pressure leak-down test also might help identify any internal fuel leakage from an injector or fuel-pressure regulator that might be allowing raw fuel to leak into the engine after shutdown. The short-term answer, is frequently changing oil to remove any soluble contaminants, including raw gasoline. That's why more-frequent oil changes are important in winter, particularly for vehicles operated in frequent warm-up/cool-down cycles and short-trip driving. At this point I'd suggest that you continue to monitor the oil, and change it frequently, until you find out what is wrong.
NO, do not use diesel oil and a gasoline engine.
Oil doesn't run cars it lubricates engines. Cars run on gasoline which is refined from oil.
A 2-stroke engine requires adding 2-cycle oil with the gasoline.
As long as the synthetic oil is of the correct viscosity for the engine, it can be used in a hybrid car. Hybrid cars have two engines - the gasoline powered one and the electric one. The gasoline powered pretty much like any other gasoline powered 4-stroke engine and uses the same kind of lubricants.
By putting only gasoline in a two stroke engine you can destroy it. A two stroke engine requires oil to be mixed into the gasoline to keep the moving parts lubricated. When you do not have that oil there it will not lubricate correctly and therefore scar and break the moving parts on the inside.
You my have coolant or gasoline mixed with the oil. You would still have oil pressure but poor lubrication.
SAE (society of automotive engineers) sets the rating for the oil. Gasoline engine oil is given a "s_" rating. SE would be a rather old rating as the current is SMSAE (society of automotive engineers) sets the rating for the oil. Gasoline engine oil is given a "s_" rating. SE would be a rather old rating as the current is SM
It gets its lubrication from the oil mixed with the gasoline.
More cars on the road require more gasoline. Gasoline is refined from crude oil. The more gasoline needed the more crude oil needed to produce it.
I am not sure what you are asking but putting oil for diesel engines in a gasoline engine with some oil in it would not be good, or vise versa
No, putting gasoline in a diesel will destroy the diesel engine.
Cars run on fossil fuels, gasoline, vegetable oil, and electricity.
