"I do not have a Suzuki dealer
"I do not have a Suzuki dealer closer than 35 miles from my boat and I do not want to travel that far just to buy two extra quarts of Suzuki 4 cycle oil. I already have one QT of Suzuki SAE 10W-40 (SP-40) and am wandering if I can buy antoher brand of marine 4 cycle oil to combine with what I already have? I know that you can not mix weights of oil but not sure about mixing brands when it comes to outboards. Lastly..could I use a regular 10W-40 form an auto parts store or are marine and automoive oils blended diferently. I have used automitve 10W-30 in Honda 225 HP outboards for a few years and not run into any issues. Suzuki just mentions that any 4 cycle oils used meet SE, SF, SG, SH or SJ under the API system."
