I was recently told that if you ever start using synthetic oil in your engine you have to continue using synthetic oil for the life of the engine. I had never heard this before and did a search on the forums here to see if this topic had been covered but did not find anything. Anyone have any info about this?
If it is true, can anyone explain to me why you should not switch back and forth?
Thanks in advance...
