One oil for all engines

So the middle of the spec today was the minimum spec 20 years ago. Do you understand what this means and why? 20 years ago the metal finish was not as fine as it is today - so "high points" could cause metal transfer at larger nominal clearances. Todays bearing and shaft finishes are much finer and more consistent. You could get a

My recommendation would also be Rotella T. Depends where you are and how cold it gets whether the synth is an advantage (OK, always better, but not necessarily ENOUGH better to make it adviseable) for you. In the southern states you could very well get by with 15W40 conventional all year round on all your engines - but 5W40 will definitely do the job for all of them.

The ONLY thing to be carefull of with "all fleet" oils is some still have zinc in them at higher levels than recommended for todays gasoline engines (which is really only an issue if they are burning oil) The new api spec only applies to 5 (or 0)base oils (and possibly

10W30), not 15 base and above. Why? becuase 5 base oils are more likely to be consumed, depositing the zinc in the catalytic converters which would possibly cause them to fail before 100,000 km. ** Posted from

10W30 or 10W40 should both be satisfactoy for that engine - the more critical thing is the oil filter - does it have an effective anti-drainback valve? If not, the lifters will clatter on startup just about every time. With a good filter, they are generally quiet regardless because they are filled almost immediately.

Have never seen it happen. Now 20W50 at zero degrees - yup, quite possible.

Me, too. This graduated pouring container from Harbor Freight makes it easy to measure out the right amount of oil from 5 gallon jugs;

I traced the molded lines and numbers with a laundry marker to make them visible. You could use water from a kitchen measuring cup to graduate it more finely than full quarts & liters.
