Well. As I said elsewhere I can not add much to the solution.
The Synthetic oil thing..
About 30 to 50 years ago one of the early synthetics used a formula that damaged seals.. Took them only a short time to realize their mistake and change the formula to a much better one.
But they myths about Synthetic eating seals, You can not switch back,and so on and so forth presist from that early failure
Which by the way was ***NOT*** Mobile one (I do know the brand but for liability reasons will not mention it's name..I will only say it is NOT Mobile 1 or any product of Mobile Oil).
If you ask what brand it was I will either not respond or "No Comment".
