Because?
Very likely you are mixing the same oils.Would anyone hesitate to do a 50-50 Frankenblend of Quaker State 5w30 full synthetic and Pennzoil Platinum 5w30?
No, it isn't. Possibly different add packs and even base oils.Very likely you are mixing the same oils.
Dont agree but thats my opinion....I buy a five quart jug and a oil change on mine is around 4 qts...I save the guart of oil I did not use and the next time as long as it is the same weight 0w20 and is syn oil I pour the quart left over in the new jug weather it is Penns...Mobil 1 or another...they all meet the cars spec. for oil...I go with what is the best deal on a NAME brand oil...A mix will work but it may not be optimal. I wouldn’t make a habit of it.
What?Just a layman's question - assume one should NEVER mix a synthetic and regular oil?? Or this that not an issue given you can buy semi-synthetic (blends?) off the shelf?
What?Any oil warranty claim will be refused if products are mixed.
Start a new thread with this worn out question.OK, but my lawn mower gets really hot and abused more than my motorcycles or cars, so what kind of oil should I use?
My honda says use Honda oil, but Honda never manufactured oils? I know they haven't made any improvements in oil in the last 20 years or they would have sent out a tech bulletin?????
I take it it calls for a straight 30? Run anything in that grade. Supertech, Briggs & Stratton oil from your local lawnmower shop, Honda, whatever.OK, but my lawn mower gets really hot and abused more than my motorcycles or cars, so what kind of oil should I use?

I had it happen more than once when submitting samples for claim testing. If the tracer element isn't present in the proper concentration, that's evidence that a product of another company was mixed with ours. Or it isn't ours at all. As far as I know, no company warranties their product when it's altered or diluted by that of another.What?
