I'm curious why mobil 1 doesn't offer sae 30w synthetic oil for lawn mower engines?
Royal Purple offers sae 30w synthetic oil,and I'm so thankful!

My assumption is that they don't see enough of a market to invest in the formulation and or the manufacturing of a SAE 30 syn.
 
A synthetic base oil in the 30 grade range will flow so well at lower temperatures that it passes sae testing to be labeled a 10w30. If the product is in the range for 10w grading it must be labeled as such.

Therefore most 10w30 synthetic are essential synthetic sae 30 grades also due to no extra pour point depressants being needed.

Amsoil lists their small engine oil as sae 30 slash 10w30.

Mobil 1 High Mileage 10W30 is a good affordable alternative to amsoil small engine oil.

No it is not.......And I doubt that Royal Purple 30 weight is not actually a 10w/30 as well. There would be no advantage in making an actual straight 30 weight synthetic oil, since it would pass grade as a 10w/30 or better anyway.

Everything he told you is correct. A synthetic 30 weight would have the low pour point of a 10W30 synthetic oil. They both operate at a 30 weight when warm. You can safely run a 10W30 synthetic in the place of conventional SAE30. Its not practical to make a SAE30 synthetic oil.

By the way, Briggs and Stratton's #1 oil recommendation for ALL their engines is 5W30 synthetic, followed by conventional oils in 10W30 or SAE30 depending on temp range.

I wonder if OP means ND 30wt???

Why don't you tell us what brand engine and horse power rating you are using so you can get better advice from the crowd?

I've used M1 10w30 in my lawn mower for the past 10 yrs. It's a briggs 7hp motor OHV walk behind mower.

Now if i can keep the dang carburetor from leaking. Dang thing has been rebuilt 2x's and still leaks.

I am fully aware they aren't the same thing but it's technically impossible to make a synthetic SAE 30 grade oil without lying about the cold weather performance.

Lucas had issues like this when they sold a 15w40 oil that passed 10w40 cold performance.

As others have said in more complicated ways

Most synthetic base stocks have a viscosity index such that they would be a 10w-30 with no modifiers. A SAE 30 or "straight 30" synthetic oil would just be a synthetic 10w-30 with misleading labeling.

Also as others have said, there is just no market for lawn/garden oils. Basically they're all just manufacterer stickered HDEO's, some that Mobil likely provides.
 
Means the oil will flow easier and faster through the engine on cold engine starts, but still gives the engine the correct vis. for hot engine operation.

The oil has a viscosity of a 10wt oil at 40C, and it behaves as a 30wt oil at 100C.

In the world of modern synthetics, there is really no such thing as a straight 30wt. The oil's viscosity index meets the 10w-30 requirements without any additional index improvers. The old conventional oils were made thin (like a 10wt), and viscosity/index improvers were added to thicken it up when it got hot to behave like a higher viscosity oil. The only difference between a straight 30, and a 10W30 is the viscosity when cold.

There is no advantage to running a straight 30 vs a 10w-30 when you are using a synthetic. It is for all purposes a 30w oil and will behave as such when hot.

That engine manual calls for a SAE40 weight oil in your Florida climate of above 68 degrees.

15W40 Delo or Rotella would be a good fit also. They are also a 40 weight at temp and have heavy duty additives that are better for wear.

If you absolutely must have a synthetic, then check out 5W40 Mobil Turbo Diesel Truck or 5W40 Rotella.
