It's said that its not good to go from synthetic back to conventional oil from what I've heard. Now since Mobil 1 is no longer a full synthetic, will the issue above be relevant? Anyone still sticking to Mobil 1 and the new Tri-synthetic and if not, what brand have you switched to?

 

I heard it was the same stuff just under a new name?

 

no longer full syn? your kidding me, where do you read this?

 

I just used their tri-syth today for the first time. Is this stuff not good?

 

or wait, I think the new one is the SuperSyn formula. I just heard from people that its not fully synthetic anymore like the castrol. Can anyone here confirm that? I'm not too familiar with it.

 

Both Castrol and Mobil 1 make a full synethic and synethic-blend(not fully syn)

 

Just changed my oil w/it Tuesday. I've been using Mobil 1 forever. Didn't notice any changes, didn't expect to.

 

i ran the tri-synthetic since new, and also heard mixed reviews about the super-sync, i've been using it and car runs the same but who knows...

 

I use it, no complaints.

 

amsoil but i use the mobil1 tri syn...havent had a problem

 

synth...best stuff to ever use on your car...don't use those regular oil...because it leaves deposits..that eventually wears out your motor...once you use synth don't switch back...change the oil every 7500 if you daily drive...every 5000 hard driven miles...

 

I used Mobil1 for about the first 25K miles I had my car. I can't get it as cheap as I used to anymore, so I just switched to Valvoline Max Life 10w30. The only reason I switched is cost. And I change the oil every 3K miles so I don't think there will be any problems w/ deposits.

 

i change mine every 3k or earlier..because even though the oil will last longer... you can feel the difference. the engine just runs better on fresh oil.
and after some time the synthetic oil will break down..of course...
i wouldn't leave that stuff in there past 4k...especially since i drive hard...

and not every synth or conventional oil is the same.

 

ya, but if you change at 3k miles, then it all does its job like its spose to
