Hi all.

Searched  "Hypuron" in archives. Didn't get any hits.

I don't know if the TBN and Low Ash aspects help a gas engine, but
looking at "Oxidation Control & Shear Stability" here:

http://www.castrol.com/castrol/genericarticle.do?categoryId=82915547&contentId=7025207

seems this might be a decent oil with a good price balance between
100% synthetic and conventional oil.

Has/is anyone using this product?

When introducing a synthetic blend oil to a an engine that's been
running NON synthetic, is there a high risk that the new oil will
cause seals to leak?

My goal isn't to extend oil change intervals. Just want to provide
better protection for bearings etc.

Neil.
