Synthetic Oil Sign In

I'm considering switching my car from conventional to synthetic at the next oil change. It has 77,200 miles on it currently. Can i just switch it like that?

I've been looking up this online and found someone saying that synthetic oil doesn't absorb as well into rubber so its possible that old gaskets with microscoipc cracks could dry out faster and fail. Someone also saidthat synthetic oil is thinner and it could cause it to leak from the valve gasket?

Has anyone here heard of that before?

I've heard the same stories. I had an Amsoil rep come by several years ago. Of course, being a salesman, I took what he said with a grain of salt, but...he sold me. Since, I've changed both of my vehicle over. No problems. I've got about 50K on my truck and about 40K on my wife's car. So, for what it's worth.....Smile

The oil is not any thinner unless you go to a thinner grade. The oil has to maintain a certain viscosity or thickness in regards to industry standards in order to qualify for a certain grade. (5w30, 10w30 ect.) As far as causing premature seal failure, I agree with Loren, haven't seen any evidence of that. In fact the opposite. Synthetics are far superior to conventionals on every level IMO.

I'm totally in favor of synthetics (BY THE WAY GUYS - AMSOIL IS THE PRIME SPONSOR HERE) and never had any added problems with it. Used in everything - yard equipment - all of it.

IMO it's best adantage heat tolerance and maintaining the listed viscosity. It's far less apt to sludge up with heat or being late with changes but not an excuse to do that. Also - hard to nail down but I swear it's more efficient.

Side note: I have a 12.5HP pull start engine that is remarkably easier to pull when it gets colder out as my own proof that it's a better lubricant,
