another synthetic oil thread, i'm pretty sure i havent seen it posted Options

[brianforster]

sorry if this is a repost but:

would it be beneficial to switch to fully synthetic mobil1 if the only real "problem" with my engine is the valve seals?

Ive read that if you have any oil leaks what so ever that the synthetic will make them worse, so will i go from seeing a tiny puff of smoke at startup to OMG the house is burning down?

Thanks all

Synthetic oil has much finer viscosity which makes it flow a lot easier. If you have valve seal problems you will get a little more smoke than conventional oil but not an absolute TON. I would continue using conventional oil becuase your engine is not performing at its best anyways. Get those valve seals fixed, then switch to synthetic. That is as far as I know but I might be wrong so you might want a second opinion.
