synthetic oil

[7.3TurboDiesel]

I have been thinking about switching to synthetic oil. Is it worth the extra bucks? Is it true that once u put synthetic oil in your cant go back to dino oil? Also what kind of rating should i look for in a synthethic oil? I have been looking at duron xl synthetic 15w40 or duron-e xl synthetic 15w40. THe duron-e xl is for newer diesel engines, will that hurt my 95 7.3?

Well that really depends what the cost of the oil is vs dino and whether you go to extended drains. If you go with a bypass filter and extend drains with sample testing then yes it could really be bennificial. You can switch back no problems. No the new rating is backwards compatible with older engines.

Last week I install an fs2500 bypass oil filter on my 2003 F-250 stroker. Am looking forward to extended oil changes using Amsoil synthetic oil.

I'd not only like to save a few bucks on oil changes but mainly I hope to extend the life of my engine. I'm not sure how much I'm really going to save though as I plan to have Blackstone check my oil at $22.50 a pop every 7500 to 10k miles. At $50k a copy for a new stroker I'd like to do what I can to save the one I have now.

You can even mix dino with Amsoil, but you wont get as much longivity as with strait Amsoil.

On an older engine that prolly has some sludge, run moter flush of some kind. Amsoil cleans the engine up and you may have to change it soon on the 1st change to get the crap out.
