Optimal RPMs?

Hello!

I just bought a 2005 CR-V 2.2 CDTi. I had a CR-V enthusiast tell me I should generally aim for 2000+ rpm when driving, for best fuel economy and to have less problems with EGR/soot filter.

Could anyone confirm if it is true? In general, when driving other (gasoline) cars, I had best fuel economy when driving at around 1500-1800. When going over 2000 it usually would skyrocket.

I see Serj22 here did say the same 10 years ago in a forum I can't link to because I have not enough posts /forums/76-fuel-economy-gas-related-discussion/4270-what-best-speed-drive-crv.html :

If I'm not mistaken, the Cr-v has always been designed to burn less fuel aat higher RPMs. Lugging the engine will cause you to lose MPG.
Would it be good advice in your experience?

I've read that to keep your diesel clean Shell regular has more detergent than anyone else's and will also give 50MPG in a 2.2cdi and you can't complain about that in 1.75 Mton car with no aerodinamics, can you.
