Jon Kaase believes in Amsoil.
At what point should i consider switching from amsoil 10w40 to the rd30? Performance mods for me are 127mm cai,lund tune,off road h pipe, and stainless works cat back.
In this weather, you can switch right now. For a street car, run it year round.
And did you read the article about Jon's winning 4V Cobra engine. It made hundreds more horsepower normally aspirated than a lot of blown Cobras make with the power adder.
720hp and 665.9tq
But my favorite engine of his is still the Boss Nine. What a great looking engine and who doesn't like 1200 hp on pump gas with no power adder.
Jimmy. Have either RP or Amsoil done a back to back dyno comparison?
Install already broken in engine on dyno. Run one of the oils for 30 minutes. Dyno engine three times.
Drain oil. Refill with other oil. Run 30 minutes then dyno three times.
That is the comparison I would like to see.
I wonder if we would even see two hp difference on a 650 hp NA engine.
And each oil manufacturer do the test in their own dyno cell with their own engine.
