It would be cheaper to just take the 30wt oil from your lawn mower and run it through a Fram filter to clean it up enough for reuse. If your mower doesn't go through enough oil, they have a big vat of the stuff used at Autozone, take a 5 gallon bucket and get some of that when they aren't looking (pretend that your 5 gallon bucket is really heavy so they think you're making a deposit instead of withdrawal).
I heard Dollar General is really "Mobil 2" oil. I would steer clear. Also watch out for Mobil 1 at Walmart. It has a different formula then other stores. My uncle's cousins dad told me it's basestocks are not good enough for 3rd world countries so they sell them at Walmart.
Watch out for the Fram's that rust on the cardboard ends.
"just bought a new $85,000 Porsche"... and don't know how to read the Owner's Manual or google either.
To be fair, people write in thinking there is some inside info or 'specially-good brew out there. That is almost true. Example: some say ya gotta run the mPAO in Driven Racing's 5w40 in Porsche, anything else is settling for less.
Guys I just bought a new $85,000 Porsche. I went to the store to buy Mobil 1 @ $23 per 5qt jug, but it was too expensive. Should I run Dollar General 0w40 instead? Thanks
You need 2 people to tell you that you should have purchased a Ferrari. One more to tout the benefits of Maserati over Porsche or Ferrari. At least 3 to tell you all the ways that Toyota is superior to Porsche even though Toyota is boring. 5 more will scold you for making payments, and one to tell you how much faster his Honda is after he put Porsche badges on it.
