Substitute the Delo for his (probably typo) $36 oil, I still get a total far less than $200.
I also do my own lube, oil and filters. My historical cost has averaged $110 without the $40 air filter.
Three one gallon jugs of same oil are occasionally on sale at Costco for $30 out by us. Normal price is around $37.
