UOA Oil Analysis - 6.3k mi Pennzoil non-synth

[SHOdded]

I didn't realize the engineering on the GT is identical to the SHO.  Heck, I don't even know all the changes Ford has made year to year on the SHO!  We find out certain things by trial & error, but would we say we KNOW what is really going on?  I think you should talk to LME and let them fill you in.

In any case, the point is if you want to do it, do it.  We are not here to force you to do anything, just provide our perspectives.  But at the same time, people reading the content on our forum should be clear that they bear the risk of such experimentation.  Of course, we are interested to hear/see what happens from your tests.  But it helps to provide concrete facts/evidence for the user coummunity to evaluate.

I lost respect for Amsoil when they brought out Signature and changed their other offerings as well. 

Why is this?

I lost respect because it appears they performed a bait and switch.  Much like Mobil and Castrol did.

When Amsoil only had one offering it was a true synthetic.  It seems to me that they then brought out Signature to make the public think that they have engineered an even better oil.  But, what they actually did was change the formula in their standard offering to a non synthetic base stock and rename their standard offering Signature.

At least that's what it seems to me happened.  I know years ago they only had true synthetic and it wasn't called Signature.  The standard Amsoil is now petroleum base stock and you have to step up to Signature to get what I, and other countries, call synthetic oil.

Agree completely.  I guess they wanted a bigger share of the market?  Signature would be the only engine oil I'd use though.  Can easily get quality non-true-synthetic oil just about anywhere for cheaper.

Had no idea. So "blended" can be labeled as Synthetic.......yikes.

In the US, they can modify the structure of petroleum and then call it synthetic.  In Europe it has to have a non-petroleum (Class IV or V synthetic) base stock to be called synthetic.

I strongly support Europe on that classification.  Otherwise, the synthetic label on the bottle is near meaningless.

I dont think it was a bait and switch at all...i think it was just a matter of expanding their product line...the OE and XL amsoil were simply created to have an offering in a segment that was previously unavailable by them

Have to diversify to stay alive sometimes.....not everyone wants or needs class IV/V oils

So now if you want the amsoil name and advantages that may come from their research and philosohy but want conventional oil you can have them as an ootion
