Difference in Oil

General Boats and Motors

I have been running Pennzoil Premium in my 2003 Yamaha 70 TLRB for the last 6 years or so. Yesterday I went to take advantage of the 40% off coupon I had but Autozone only had the XLF (Extended Life Formula) so I bought it. What is the difference and will it matter if I start running the XLF vs the Premium?

Thanks

I was a diehard Yamalube fan for the first few years of owning the very same motor (just a year older). I gave it up and have been using the XLF for quite a few years myself with good results. Truth is, my motor actually smokes less on the XLF than on the Yamalube. I think the difference between the Premium and XLF is the percentage of synthetic oil per gallon.

I’m so excited I can barely cope,

Does it hurt your motor to have different kinds running through it? Is this not a good idea to ? I pre mix my own and usually use the same kind but sometimes ill switch it up. Ive never had any problems.
