Amsoil with a hint of castor would be ideal. Amsoil without castor in any engine other than our happy time chinese garbage not so good. Don't blame the oil, I blame the metallurgy and poor chinese quality.

BITOG....a site that anyone who has ever poured a quart of oil in their vehicles should read religiously. I see Pablo's postings there and on tdiclub often. Small internet, isn't it?
