The reason, I was told if you have high milage, synth can wash out carbon in the cylinders and cause lower compression thus not leaking oil but loosing it past the rings. I switched at 80K and I cant keep the oil at the full mark for more than a week or two, but it will hang at the 3/4 mark for weeks on end, I have no idea why.
oils today have detergents both kinds.I think it helps alot. I use Mobil 1 and I go 6,7,8K on an oil change.
Just a little story, TRUE by the way. Years ago I used Amsoil allthe time it was the only Syn on the market that stated a 25K oil change NOT the filter just the oil.My buddy ran a change to 28K then sent 4 oz of the oil to an oil analysis lab in South Jersey. they sent back his results. They said he wasted his $$$$ changing his oil it still fit the specs for new oil. Yes it was still dirty, he used Amsoil filter changed out every 6 to7K. It changed the way I see oil.
One more tid bit. I know a guys who used a dual remote (1 qt filters) under the hood and he never changed his oil per say. Once every other month he spun a new filter on and added 1qt THAT WAS HIS OIL CHANGE. he used Mobil 1 and only ever had the drain plug out once, he sold the Dodge Ramcharger with just over 300K on it.
