Can't find 30W oil anywhere in my area, or on line.

[Alex Ethridge]

Again....10W-30 IS 30 weight.

They are different or the manufacturers would not recommend one over the other.

I kind of like the 2nd reply here:

It makes sense to me. How many old pieces of equipment are still around and running, that were always fed 'a good grade of 30W motor oil', a phrase I remember from somewhere? Which pieces of equipment are the ones that fail? Just by observation, with no statistical basis, hearsay if you will, most that die are the ones that were NOT fed oil at all, or were fed oil that was old after the first year of use. I.e., the oil was either lacking or not changed.
Very few failures are due to the design or manufacturing process, most being due to abuse by an ignorant(or lazy) owner. Of course there are exceptions.

If it calls for 30W, dump in something that is decent, and change it at reasonable intervals.

When these engines, even new ones, were designed, the extra cushion of temperature stability provided by synthetic lubricants was not even considered as the cost per quart was multiple times that of regular oil, and regular oil met the needs with a good cushion. Using synthetic is a personal choice, and is up to the individual. I *think* most failures are due to owner/operator considerations(or lack of), not the grade/brand/type of oil.

I'm looking for Castrol 30W oil and cannot find it anywhere, on-line or locally. I've checked AutoZone, Advance, O'Reilly, Walmart, Lowe's and Home Depot. So I decided to try for other brands, brands I recognize, not this cheap unknown stuff. The only straight 30W I can find is Super Tech but I have seen the independent wear test run on it and is ABSOLUTELY NOT as good as the nationally-recognized name brands.

You should be using 4cyl oil for air cooled engines.

I have been using this for over 4 years off & on. Now it is all I use in my Equipment that requires 30w oil. Haven't had any ring, valve or other issues. I do change oil regularly.

I see Castrol HD 30 Monograde Conventional Motor Oil at Walmart online. Its expensive though at $19 QT. Ebay has better prices for it though and free shipping.

There's not one thing wrong with using Super Tech in a lawnmower. It's not a Formula 1 racer turning 10,000 rpms. It has the spec.

The SuperTech may not be as good as some national brands. Well, you can do your changes on shorter intervals if you feel it does not provide adequate longevity. Checking the links, $10 for a quart of Pennzoil is a bit much for me. The Walmart links are less pricey at least right now. I cannot understand $40 for a gallon of 30W, no matter the brand.
I'd use the SuperTech as it meets the standards specified. These machines are not in the same class as a 1911 Harley so should not need more than the manufacturer required. To each their own as likely no one will agree with my comment. I use SuperTech 30 non-detergent in my B&S branded china compressor. Lots better than the muck that was in there when I got it.

Plus, nothing used or leaked oil more than a 1911 Harley! So, quit wasting money on stolen oil resold on eBay for $40/gal.

You have my permission to be of that opinion.
