Great question Cody! This Powercare 1 Qt. 10W-30 Small-Engine Oil is Lubricant for 4-cycle air-cooled engines that require Premium grade 10W-30 oil. Thanks for asking! - Eve
Hi Kathy, Thanks for your question on the Powercare 1 Qt. 10W-30 Small-Engine Oil. How long the oil will last is based on the usage of the generator. The RYOBI RY906500S 6,500-Watt Gasoline Powered Portable Generator has a low oil sensor causes the engine to stop if the level of lubricant in the crankcase is insufficient. Please see the User Manaul under the MAINTENANCE SCHEDULE for instructions on how often the oil should be checked or changed. I hope this helps. - Eve
Manufacturers add a brown-colored dye to engine oil so it can be distinguished from other fluids (transmission, coolant). This particular oil doesn't have a dye, which is why it looks clear. I have been using this oil on 2 inverter generators without problems.
Hi Sam! This is Premium grade 10W-30 oil. Please check your manual for reference of what oil you will need. Thanks- Eve
Hi CRTX, You should always follow the manufacturers specification for oil in there motor. Thanks for your interest. Greg
Hi Rhy22, This oil does not have ethanol. Thanks for asking. Greg
I have had unopened bottles for more than two years work fine when opened. I have had open bottles three years old that also worked fine when used.
Hi Edward, This should be fine for that if it suggest the 4 stroke oil. Thanks for asking. Greg
Yes, but if you want this specific brand it is in a smaller container. Home Depot does carry other brands of synthetic oil in quart size.
