I bought Del Ray engine oil , 20 50 standard for Harley....and I went to repair shop to get more....They told methey dont have the del rey oil in canisters anymore...so he just filled my old container with new oil....
Is it safe to use same 20 50 oil even though it is not del rey?

 

Any 20w50 oil can be used, mixing brands is fine.

 

A rare one... an oil thread virgin?

 

I`m guessing that the op is from a part of the world where oil brand choices may not be a simple as where we live.

In some places you gotta take what you can get...

 

yeah exactly.....we even have 20w 50 salad dressing oil......so maybe i will start with that cause it is cheaper

 

Can't mix oil types or disastrous results, Harley used to say you couldn't switch to synthetic. Next thing you know Harley is putting synthetic blend in the high dollar bikes from the factory.
You'll be fine.

 

there are several oil stocks. can you mix them??? if in doubt, just change the oil so the machine is majority the same.
if you are doing oil analysis, it does make a diff since your trend is based off a oil sample you supply when setting up. if you switch brands, best to submit new base sample.
oil has come a long way.

 

 

next time i go rent a bagger I will use olive oil

 

Except for the synthetics oil is oil. It all come out of the same ground.
