I always used Lucas and it's a good product.
What are the Credentials of this Bobistheoilguy other than him playing with the Gear toy?

Bobistheoilguy is not a he - it is a them.

yeah ok-whatever
Really scientific of them showing someone spinning the Gear toy with no real research on Real Engine components.

No different than the "demo display" that Lucas uses.

and this Bob whatever is Heavily sponsored by Castrol which is a Huge competitor to Lucas.
This smacks just like when a company Just happened to have a Alternative to Freon way back when and they Paid a Environmental group to Protest the Use of Freon because of "It's Harm to the Environment" and Wa la-This new companies products became the new standard for A/C.

That's a conflicting statement??? Since when does DDC recommend a lucas additive?

The truck OEMs have overstocked '06 engines intentionally. The '07 DPF engines only HAVE to be installed in 01/01/07 chassis.

Maniac, Thanks for that link...

Most guys started buying Lucas based on a hand-cranked toy that shows similar to the example. The difference is that his spins the gears at a real-life speed as opposed to "idling across the yard" speed.

What a shame, huh?

...and don't forget to add ; 134a does a tiny fraction of the damage that r-12 caused, and is much cheaper. Our environment will be thousands of years (or never) recovering from r-12 damage, and it's still being used in some countries.
