I found 10w to heavy still. I use a 5w-30 or40 oil. Nulon or Castrol for me

Can you explain " I found 10w too heavy"

 

[RustyNav09]

Heavy as in to thick for startup. Even though its graded for our climate and all mechanics use this grade unless specified I found that I had a bad engine rattle to long with the 10w stuff. The thinner stuff doesn't seem to rattle as long and the tensioner adjusts a lot quicker.

Normally Rusty it works the other way----heavier oil reduces rattling..due to the xtra stress take to shear heavier oil..remember viscosity is only a shear value

^^that may be the case, but heavier oil will take longer to pump around the motor. It might reduce rattling when warm, but when cold the longer it takes to build up oil pressure the noisier it will be...

works the other way as well..pumps are positive displacement
