So I have a partially used 5 gal jug just like above that has the "FS". So thats what I put in at this latest OCI. However, I also have a partly used 1 gal bottle that does not have the "FS". So all or some of the reports you see in my Blackstone had the "non-FS". I got all my oil from O'reilly or AutoZone so when ever this "FS" hit the market I assume I was using it from fresh store stocks.
When did this stuff come out?
I would never have noticed this if not brought to my attention here.
Now I have to worry that I have been using the old formula and only now have the FS in my motor and my results will turn to [censored] on next Blackstone !!!!!!!!!!!!!!!!!!!!!
What is different in the new formula ????? Can it be determined from my additives in my report????

Here is a long thread about it

I run this oil too, everything I've read, it should be just as good or better for our LS engines. You will find out soon though, everyone will be excited to get a comparison.
Well read some of that. Its mostly over my head. I see that the FS came out in Feb. Wish I had known about this then so I could have documented if I was using the old formulation or not. I'm hoping Mobil knows what they are doing and that the FS will work as good or better. But definitely I have the FS in there now.
