i have heard nothing of the sort about synthetic stopping leaks.
however, i have always assumed that synthetic has detergents in it (as well as being more viscous) that can break down gunk that previously was sealing a leak. and it's more viscous property allows it to seep through the leaks that it just unplugged.
with that being said, yes. switch to synthetic. i did at 124k miles.

No you don't have to run any cleaner when switching oils. I have had mine on a diet of synth for years. I have decided to go back to conventional so I mix 5 quarts of castrol GTX and 2 quarts of Syntec. I also use an oversized Amsoil SDF filter. All of it is 5w-30. She runs like a top still and I drive her 100+ miles a day. No leakage, no problems. I put the Seafoam in my gas tank 2 weeks ago to clean the fuel system and injectors. She is running great!

How can I put this? WRONG WRONG AND WRONG. Only high mileage oils will swell seals and if you switch back to a regular non HM oil then you can have leaks form.
Syn will not cause leaks but might show where leaks was before but was clogged by build up around the seal. I have switch my truck from SYN to Dino and back again with no problems of leaks or any problems. Thats an old wise tale. You shouldnt have a problem switching to syn just as long as you kept up with the OIC's.
just watch it a while and make sure you dont have any leaks form.

Just like jecht said switching back and forth won't hurt shit where does everybody get these rumors from? Oil these days syn or dino has detergents in them long time ago oil was non detergent but it won't hurt to switch at any time. I ran gunk in my engine before switching to synthetic but you don't have too.
Turbo blew your post kind of sounds like "only you can prevent forest fires" LOL

When Switching to Synthetic Motor Oil - Please Consider Amsoil.
__________________
Switching to Synthetic Motor Oil
Synthetic lubricants do have an inherent detergency that cleans and removes conventional motor oil deposits (crud) left over in an engine that has not been well maintained. If an engine has not been maintained properly and there are damaged seals and the crud has created a "fake seal" then you could have minor leakage. However, ALL motor oils are designed (with additives) to help swell seals slightly to prevent leakage. The ONLY time you would observe seal leakage when switching to a synthetic oil is if the seals are already damaged or showing signs of leakage around them. As long as the vehicle has been well maintained, and in good mechanical condition, it can be switched to a synthetic lubricant at any mileage.
Has your Dakota been well maintained, and is it in good mechanical condition?
If so ... you can switch to synthetic motor oil.
(not directed at you Jecht ... just offered to everyone as an FYI)
It appears that many owners are going to "high mileage" oils for no reason other then they have a high mileage engine ... whether or not their engines are demonstrating problems. Most "high mileage" oils are just basic conventional oils that are formulated a bit on the thicker side of their respective viscosities, plus they add about 10% esters in the base oil for their slight seal swelling effect (which is very very minor I must add). Some people are switching if their vehicles are consuming oil. The main reason people see reduced oil consumption (using high mileage oil) is due to their thicker viscosity. Most of these oils appear to be marketing gimmicks. I am not saying they are "bad" oils ... just gimmicks.

Ah...i see...damn economics!
I guess Royal Purple & Mobil 1 are made in Canada and weren't affected. Royal Purple's the same price as Mobil 1 now, with Amsoil being the highest of the syn's.
I might give Royal Purple a shot...hell, for $20 bucks less per change...

not a problem. Just saying that I heard about the seal swelling from HM oils on another oil site I goto. I was just letting him know that SYN wouldnt swell seals like the other person said. Either he got it mixed up or he just dont know or going by wise tales of the past.__________________

Pugsy,
I currently sell Amsoil 100% Synthetic 5w-30 (Code ASL) for $9.70 / quart [Canadian $]
I currently sell Amsoil 100% Synthetic 5w-30 (Code ASL) for $6.75 / quart [U.S. $]
Amsoil is cheaper per quart by the case, gallon, 30- or 55-gallon drum, or 275 gallon tote (if interested).
All lubricant prices have been volatile recently, and we have worked very hard to keep our prices competitive.
Thank you!
