I use different oils from this manufacture-
Welcome! because I have a cheap local source for it and they keep it all in stock and it is good stuff. Pennzoil 10w-30 when doing work for contractors if they have a bunch of OHV powered small equipment since it is easy to find. Any HP 4-stroke dirt bikes I do get oil from Spectro Oils as well as all my 2-strokes I stick with Golden Spectro-been using this one since 1976. Funny though if you do some research on 2-cycle oils for say those Para gliders and the like they ALL ONLY recommend the Pennzoil 2-cycle.
Funny-last fall I was helping out at a local mower repair shop and we did a new long block on a Briggs powered riding mower. Informed the customer that the oil would need changed after a short period of time due to break-in and that. Well the customer got some hours on the engine and proceeded to the local Wal mart and asked for a "Good" oil to use and explained what for. The employee at wally world must have figured that "Good" was relative to cost so they sold the mower owner enough oil to do their oil change-in the form of 6.4oz bottles of 2-cycle oil. Needless to say that was a very bad choice.
The Briggs rep had tears in his eyes from laughing when he saw the carnage and the customer had tears in their eyes from another $1200 bill.
Funny that new Briggs lasted about 20 minutes with the 2-cycle oil in the crankcase-sad but true.
