There is no good reason you should, and there is no good reason you shouldn't, other than maybe marginal decrease in fuel economy.Is there really a good reason I can't use 0w40 A3B4.?

It's not going to hurt anything and might be worth trying if you have cold start piston slap like most 3.1 engines.My 03 Buick century 3.1 specs 5w30 only. Is there really a good reason I can't use 0w40 A3B4.?
What temperatures are you starting your mower? Unless you're near freezing the viscosity between the two is nearly identical with the 40-grade slightly higher at typical mowing temperatures.Thank you. I changed my push mower and riding mower from 10w30 to 0w40 last year. So far start w a y easier. I haven't had to add any oil.
With 130k on the clock … not a bad idea. Made that switch on our Cruze at 100k … quieter …I would like like to use 0w40 A3B4. I would just like to know if there is a reason they say 5w30 only.

Car is not modified. I am 70 and need it to last as long as I can drive.

Jumping from xW30 to a3/b4 xW40 is kind of like skipping 2 grades. Take it easy, do it one at a time
I switched all our vehicles to 0W-40 (look at my signature) to overcome their shortcomings and design flaws and have not noticed any negative Ill effects. The fuel economy is the same as before, or slightly better. Truth be told, 0W-40 is a nearly universal motor oil.

Also, you tell the man to go with 10W-40 , but not 0W-40? What kind of non-sese advice is that? It's like saying "don't go thick on your oil, go thicker!"
