Idling Effect on Engines
Posted by Super from New York, NY, USA on April 6, 2007
How does idling the truck for long periods of time affect the engine?
Where ever possible engine idling should be minimized, as excessive idling can result in dilution of the engine oil with fuel, increased soot generation, and occasionally formation of water condensates. Water and fuel in the engine oil will reduce the effectiveness of the lubricant to lubricate engine parts, and soot will make the oil thick and abrasive. This is on top of the extra amount of gas that is consumed compared with starting and stopping the engine. If heat or cooling of the cab is required consider the use of a stand alone cab heater / cooler.
How does the fuel get to the engine oil?????
whom ever wrote the first part of the answer is very wise.
The fuel gets into the engine oil from various sources, some from leaking fuel pipes, but mainly due to incomplete combustion. Everytime the the fuel injector sprays a small amount of fuel gets onto the cylinder liner wall this is then washed doen into the engine sump pan when the piston sweeps past.
Oil weights

This is out of the line of “trucking” but if you are an “Expert” on oil I want to see if you can answer this question.
This is for oil used in a motorcycle. The Yamaha book calls for 10w30 from 10 - 90F. 20w40 in temp. above 90. I have searched but all I find is 10w40. Is that safe to use or can you blend weights to achieve a 20w40. The engine only holds 3.28 US qts. We are planning a 8000 mile trip so oil changes will be made every 3000 miles.
In theory you could blend the two oils to meet the correct viscosity, but this is not reccommended for two reasons,
1. the oil additives within each oil must be identical and in the oil at the same quanity in order to ensure the performance of the oil is uncompromised this is very unlikely
2. The amount of 10W30 and 20W40 that needs to be added to reach the correct blend would be very dificult to calculate, as the viscosity of a finsished formula is the result of base oil, viscosty modifier and additive pack.
A 10W40 sounds like the perfect viscosty for your motorcycle, as this combines the cold performance benefits (for starting) of the 10W and the hot tempereature performance of the 40.
