I would not use diesel oil in your gasser. I tried it in my 500sec and it made the hydraulic lash adjuster stick and tick.

I took it out and put in Mobil one 10w30 and the ticking stopped.

I went back to the rotella thinking that now its clean and it wont tick, but it immediately started ticking again.
