He was told he can use synthetic oil in the engine and I wonder. He only drives it about 1500 miles a year and plans on changing it every 1000 miles. Any comments? | | | | | Joined: Feb 2004 Posts: 29,881 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,881 | The burning question would be "Why?" The main advantage to synthetic oil is its extended change interval in new, tight-clearanced engines. That one will contaminate the oil with blowby and corrosive combustion gases in a very short time, so frequent changes would be very much in order. Also, I doubt if synthetic oil in a heavy enough weight to work properly in a wide-clearance engine like that one even exists. I would think a straight 30 weight oil would be indicated, and I've never seen a synthetic in that configuration.

It's driven 1,500 miles a year and he changes the oil every 1,000 miles? Why bother with synthetic oil?

Quick note, Royal Purple does make a straight 30 synthetic, as does Amsoil. Amsoils 30 wt is listed with their Deisel spec oils.

Of course, it is his money but I wouldn't do it. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | A buddy has an original 1936 truck with the four cylinder. wait a minuit, what kind f truck are we talking about here anyways???
