Something about this recommendation just doesnt sit too well with me. Just as the detergent straight 30 weight. They must have done some pretty extensive testing their,but 5W-30 Synthetic is a whole lot different from straight 30 weight. As I mentioned above,my Toro sounds best on the straight 30.
To me, 30W is old school. I haven't bought a quart of 30W in over 40 years. (I am almost 74 years old) I have used synthetic oil since it came out back in the 1970's.
I used M1 5W30 for the first 8 years of my present lawnmower's life. It has never used so much as a sixteenth of an inch of oil in a yearly, 55 to 65 hour, OCI. A couple of years ago, I ran out of my old stash of 5W30 M1 in the SL formulation, and I change over to M1 10W30 High Mileage oil. Still no oil usage in my usual yearly OCI.
I gotta admit, tho, that my mower is equipped with the consumer grade Honda 160 GCV OHC engine. It has always started and ran perfectly. It gets yearly oil changes and air filter changes. I've changed the spark plug once. I've never even seen the carburetor. It's on its second hour meter. They seem to last a little over 5 years before the unreplaceable sealed in battery gives out.
Mower is now 10 years old, with 540+ hours on it. I just replaced the front drive wheels for the second time. They seem to wear absolutely smooth and lose traction in about 5 years. I kinda wish this Honda engine would wear out so I could justify getting myself one more new mower before I pass on. From what I hear, a nice rear wheel drive mower would make it a lot easier on me during these hot 95 to 100 degree days.
