Re: what oil is recamended for 200k +

Re: what oil is recamended for 200k +
Actually Jerry is correct as far as his vehicle (with the 4.7 liter engine)
is concerned.
That being said the OP does not have a 4.7 liter engine.
If we want to post criteria for engines other than the one in question I
will state positively that my lawn mower calls for straight 30 weight engine
oil and my snow blower uses 10w-30 motor oil.

That being said the OP does not have a 4.7 liter engine.
If we want to post criteria for engines other than the one in question I
will state positively that my lawn mower calls for straight 30 weight engine
oil and my snow blower uses 10w-30 motor oil.

Actually Jerry is correct as far as his vehicle (with the 4.7 liter engine)
is concerned.
That being said the OP does not have a 4.7 liter engine.
If we want to post criteria for engines other than the one in question I
will state positively that my lawn mower calls for straight 30 weight engine
