Oil film longetivity on cylinder walls

[flying kangaroo]

Hi every one,

Does any body know that if a motorcycle or car engine is left unstarted for 4-6 weeks, if the oil film on the cyclinder walls is still there especially if you use synthetic oils for a long time as surely its not bone dry ??? as to prevent dry starting. I would imagine that the oil control rings scarper rings as some for of oil still for lubrication until oil pressure builds up ??

maybe it's just late, but I have no idea what you're trying to say.

Hi Ivymike,

Thanks for your reply to my post.

My concern is this !

Last year My 4 cylinder bike was sitting in the garage for 6 weeks without being winterized or started at all.

After 6 weeks, instead of changing starting the bike and letting it warm up to do the oil change. I drained the oil and changed the oil filter without starting the bike at all after all this time.

When I started the bike the oil pressure light was on for 3 seconds until oil pressure was built up. So my concern is if any motor is left unstarted for 4-6 weeks then the oil and filter changed then does the cylinder walls after this period still have some thin film of protective lubrication until oil pressure builds up after 2-3 seconds

Thanks

Heck no. The film thickness on the walls will be negligible after that time period. It probably would have been better if you'd started the bike for a few seconds before you changed the oil.
