I use this in oils that are not SG rated---https://www.zip-corvette.com/zddplus-oil-additive.html?gclid=EAIaIQobChMI9qiG7OKy2wIVhZK9Ch2PIA4qEAkYBSABEgKeYPD_BwE I have used this one too----http://www.agkits.com/lucas-break-in-oil-additive-tb-zinc-plus-10063.aspx?recrawl&gclid=EAIaIQobChMI4K6L0uSy2wIVg5S9Ch1bTQAFEAkYAiABEgJTPfD_BwE#.WxFnQIoh3IU
That data sheet is 5yrs old but if it has changed they would have a newer one on record. Never had a problem yet using that oil, even on 8V flatties.
Ya, I realized after I postedBut I did get that off their official site...so...you think they would update it...? *shrug*
Dave,As you know (since we're brothers), I've been using Motul 7100 4T in my Cali 1400. I just looked a quart bottle that I have on the shelf and it says "APA SJ/SL/SM/SN*" The asterisk statement below says, "Backwardly compatible with previous API Service Categories"Jeff
Why not just use the Guzzi specific SG rated ENI i-ride 10W60, it's loaded with zinc and phosphorous perfect for flat tappet motors. If the bike can take 15W50 then Mobil 1 15W50 contains 1300 ppm zinc and 1200 ppm phosphorous (see pg 3 in this pdf): https://mobiloil.com/~/media/amer/us/pvl/files/pdfs/mobil-1-oil-product-specs-guide.pdf
So it goes from SG to SH to SI and so on so anything higher alphabetically meets SG specifications it's just that much better.
