  • Which oil to use in an air cooled engine

    I've got a bobcat 225 with a Subaru engine. I've been reading a lot on the lack of zinc and phosphorus in the the new car oils so I found here local valvoline vr1 racing oil 10w30 it's higher zinc phos. Just wanted to make sure this type is alright. I got the silver bottle
    Zinc 1472 ppm
    Phosphorus 1544 ppm
    Moly 3 ppm

            I just found an oil additive from STP. , that is a Zinc additive ( ZDDP ), so will try it out. I added it today, so I will see.

              I don't care for additives like zinc. Really it's 2 litres and generally the oil is changed out at intervals. Sooooo, additives are costly and pointless. It's not like my 7.3 lt diesel that takes 17 litres on a change...

                Better off to start the thread with Oil for Air Cooled engines.. , never the less using the correct stated oil will make the engines wear out significantly less. I've seen many engines outlive their owners. Talking about 12k hour plus now. Still running like new. I've also see guys with automotive oils lasting 2k hours befor a crash, on completely rounded cams.

                    Well when I started looking around the net I read all kind of stuff . Some were saying there starting to pull the zinc out of diesel oils also .
                    I wonder why they don't just have what's in the oil printed on the bottle . Is it some kind of secret ?
                    Yes I should have said air cooled engines so it could cover generators too. Maybe the moderators could change it so there could be a good thread for people to find.
                    I've always used sae 30 wt as the manual says but never did find how much zinc was in it and I looked every were.

                      Got a message into the moderators to change the title . This is a pretty big deal these engines ain't cheap and need to be taken care of the best we can.

                        if you do a search on "high zinc air cooled engine oils" you will find a wealth of products and info...

                        not only industrial & motorcycle engines are high stress users needing extra protection.... there are also air cooled aviation and automotive engines that fit the category ..... Porsches and Bonanzas need extra protection too ...

                            But still people use car oil for thier air cooled engines, and wonder why they heat up so much. Even Kohler oil in their own kits is crap. and no you won't find any spec on it. I think basically because if their engines don't break down, they won't sell any

                              I read the articles, now does that mean I can run automotive oil in my Diesel. I know, that my engine will soot up and merely blow up. I know that if I run Automotive oil in my $10K Texas chopper engine, that it'll blow up. And I can show you a Cam from a Kohler, run with diesel motor oil all its life, merely pulled as the engine outlived the generator at 12K hours and one at 2200 hrs with Castrol auto oil. Pulled because the engine was simply done.
