mobil 1 ok at 75000
At 70,000 miles I had a long block installed by ford so the motor technically only has 5,000 miles, should I use mobil 1 oil? Somebody told me not to use mobil 1 on a vehicle after 50,000 miles.

Last I heard (years ago), was that the seals/gaskets leak. Total bunk.
Anytime someone tells you a so called "disadvantage" of synthetic oil, go to the companies web site and read their FAQ section. They address and debunk these myths.
For the record, synthetic oils can be mixed with dynos, meaning they can be used in any engine, at any time, at any mileage. Yet another way to look at it is that you could do an oil change today using non-synthetic, then switch to synthetic on the next oil change, then back to non synthetic. You can even use half synthetic and half non synthetic at the same time.
