But oil weight is not oil weight. cSt is cSt though.

I've had the most consistant results that are easier to dial in with PTRC fluids. Sometimes I feel like Ae and Losi fluids are bottled wrong. (30 in a 40 bottle etc. etc.)

(CST)

Im running Losi fluid in my bomber oval car and stock SC10.
The Losi fluid is a little more higher quality than the AE fluid.
The losi fluid doesnt leak out as fast as the AE fluid but it still leaks and is the same consistency.
I filled my bomber gear diff with 50,00wt losi diff fluid and it hasnt leaked out yet. Any gear diff will leak thou, unless you use Associated green slime.

I have been back and forth on oils. I prefer the Losi mostly cause it doesn't foam up as bad and the air bubbles rise quicker.

This is what I thought was the case. I use Losi oil in all my cars. I like the fact that different weights are different colors. I have been known to forget what weight oil I have in my shocks.

Also, if the oil was dark when you changed it that means it was dirty. Happens to all shocks over time.

+1. I've been running PT RC Racing oils for over 6 months now and I couldn't be happier. Consistent from bottle to bottle and they are available in both 2oz and 4oz sizes.
