I switched to full synthetic engine oil in 2001 and have no oil leaks on my 1995 Ford
What makes you think you will have leaks? And if you think you will have leaks then why would you use synthetic? You will have no leaks that you would not have with conventional oil.
High milage motor oil has extra additives which help prevent oil leaks.
until 1984 the pan gaskets timing cover seal, and valve seals were made of rubber. synthetics will break down the rubber compounds and cause leaks. U can use a synthetic & motor oil blend with less chance of leaks.
Synthetic or Conventional is your choice. If you have no major engine oil leaks and the engine is in good condition then consider using a Quality Synthetic like Amsoil. If the engine leaks oil then have it fixed first. Till then I would recommend using Castrol GTX 5W-30. Hope This Helps.
Synthetic oil can be used in older motors, but if you have any small leaks, they will get significantly worse. I'd recommend a High Mileage blend like Valvoline Max Life or something similar.
That is a personal choice as to Synthetic vs Conventional, if I'm not mistaken it calls for an SAE 5W30. If the engine has NO Major Oil leaks then I would use a Synthetic Motor Oil 5W30 or even a 0W30. Hope this Helps.
10W-30 is preferred. The rest depends upon you Synthetic or Conventional (dino). I side with the Synthetic better engine protection. As long as you have no major leaks, should be fine.

That's okay.
It is a combination of synthetic oil and conventional oil.
No, you can even mix synthetic with conventional oil. It will do no harm at all.
If you have leaks then get them repaired and till the leaks are repaired use a conventional motor oil.** Castrol says to use GTX 20W-50Mobil says for Superior Protection Mobil Clean High Mileage 10W-30 If you have no leaks then use a Synthetic.
