What does hotshot's secret additive look and smell like?

[sinner6.0L]

For anyone out there that has used this additive I need your help. I have a 6.0 with some a large amount of a possible additive in the crankcase I can't identify.

The oil in this truck has a smell similar to gear oil but not identical, it also appears to have a dark green tint. It's not a fuel or coolant smell, not even close.

Sorry, no ideas here, just curious what you find out on this......

What issues did you have that made you suspect a oil additive?

HSS does have a green tint, but doesn't have a gear oil smell. I just smelled the bottle I have on the shelf in the shop and it has more of a rubbing alcohol smell. I bet you have synthetic gear oil in the crank case from what you describe

Just pulled an open bottle of Mobil 75-90 syn and mixed some with a little used Rotella T6. Had a green tint and the smell of gear oil. I miss my chemistry set.

I put coolers in this truck 2 weeks ago. Fresh oil change that has 120 miles on it. It came in today owner states it's losing coolant and oil is milky.

The truck is not losing coolant or consuming it anywhere. The level is right on min with the added-on sticker and it holds pressure hot or cold. When I pulled the oil dipstick I immediately knew something was up. The oil reeks but it was at the correct level. So I drained a quart out to see what it looked like and it definitely doesn't look like 120 mile oil. It's dark, has a greenish tint and a very distinct smell I can't put my finger on. It doesn't smell like gear oil, but it's the closest thing I could come up with.

This truck left with some pretty bad stiction issues but it has returned with no concerns whatsoever. I know I didn't put gear oil(or anything else) in it but there's something in the oil that doesn't belong or doesn't seem to affect the way it runs. This is the main thing that's making me suspect an additive may have been put in the oil by a driver without the owners knowledge

it was late in the day and we didn't have a chance to contact the owner about what may be in the oil, whatever it is we'll find out.

Keep us posted. You know Rotella T6 syn has a very strange smell. Maybe they changed to a syn oil after you released it.

The color of the oil is slightly off so I know something unusual is in there. Then there's the smell. I run syn in my truck and while it does smell different it's definitely nothing like this.

It's a familar smell but I just cannot think for the life of me what it is or what it is comparable to.

I'd like to know as well. A fleet truck I assume since the driver is not the owner? I see few drivers that care enough about the equipment to do anything with it.

Just curious, but what will happen if some kind of additive was used? Or what will happen if something else (like gear oil) was added? With the warranty claim or bill?

Post the smell, maybe one of us knows what it is . . . :
