Motor oil V6 Cologne

[Stratman101]

What motor oil are you all using in your V6 Cologne motors? I read somewhere Jose recommended 20/50? Is anyone using it? Any other recommendations?
Thanks all in advance.
Btw: My tappets seem unusually loud.

I like 15w 40 shell Rotella. But climate may have some determination as to what you use.

Hi Dan. Im in Washington state moderate temps here. Are you using t6?
Thx

My Blue Boy 2.8 V6 runs nicely on Rotella

Every engine is different and the right oil for one can be totally wrong for another.

The right oil will not exceed 75 PSI on a cold start, will maintain at least 20 PSI at idle when stuck in traffic on a hot day and will maintain at least 10 PSI per 1000 RPM when running hard on a hot day.

A thermostatically controlled oil cooler may be necessary to meet those pressure requirements and about 1200 PPM Zinc is a good idea for a flat tappet camshaft

Dan. Are you using T4 or T6? says diesel motor oil.

T4 tipple Z in all of my engines. Bulldozers, Dump Trucks, Backhoes, etc.

These V6's are very noisy, solid lifters are that a way.
