Ok its the summer time, and lately its getting hot out side. I just got my 7 last thursday from my brother, and I'm going to need an oil change first. I don't like going to jiffy lube, oil can henry and all that cuz they messed my moms car up. So my question is what type of oil should i use when its hot out like this? I heard that using 10 30 is bad when its hot out, but to use that when its starting to get cold. Any info would be helpful

 

I use Penzoil 20w50 nice and thick

 

Shell 20w50 all year round. Works great

 

search please next time, as this info is posted in the FAQs...

Grade is not only it.

Use MINERAL BASED oil only. Otherwise it burns to fast and scrapes your housing around the exhaust port. You can also remove the OMP and clogg your holes with screws and use 2 cycle oil mixed with your gas. Its cleaner for the engine also.
Mix is 1/100.
Example, 50litres of gas with 500ml of 2 cycle oil.

I've been doing this for the lst 3 years and it runs great.
