When I hear that an auto parts store(AAP, AZ, PB's) is removing a particular line of motor oil(Cheap!) as to make room for another line of oil or an oil that will supercede the oil that is being removed from the shelves, all that I can find lately is 20W50 and sometimes 15W40. I only have cars that require the normal 5/10W30 and a lawnmower and snowblower(both are MTD with Tecumseh 5 & 10 hp). Is there any reason to purchace the 20W50? Maybe use a qt here or a qt there? Otherwise I just pass on the oil. Sometimes I'll get a couple of qts of 15W40 for the lawnmower.

I buy any closeout 15w40 or 20w50 just to mix it with 5w20 oil. No loss in gas mileage when I use 1 quart of 20w50 with 3 quarts 5w20.

Maybe next time I get a good score on some light weight oil(5W20/5W30) I grap some 20W50 or definatly 15W40 and blend them together and try it.

For older engines and those that live in hot climate area. Check your owner manual and you might see 20W50 as a recommendation for hot weather.

X2, for Rochester NY, 20W50 or 15W40 are not advisable even to thicken the 5W20. For FL or AZ or TX, it is probably ok. 15W40 is mostly for Diesel but if you own a Diesel in colder climate, the 5W40 synthetic is suggested. Just my 0.02.

It exists so guys with nothing to do can ponder the question of why 20w50 exists.

Motorcycles, outdoor power equipment, high performance engines, older worn engines. The list goes on.


There's no such thing as:
Too big of a battery,
Too large of a gas tank,
or too loud of a horn,
or too bright headlights.

I have 3 cars that take 20W-50. They all are Citroen cars with the flat 2-cylinder 602cc air cooled engine and date from 1964 to 1986. That engine was manufactured as late as 1990 in the Citroen 2CV. That's why I need it... :-)

I used it in my 74 Beetle and it's in my lawn mower right now.
