Spring came, and I decided to do some internal cleaning;
I want to put some additives into oil, gas, and whatever else you would suggest me to add. what are the best brands i can get?

Some Chevron Techron in the gas tank. Nothing in the oil but the best full synth ACEA A3/B3 rated 0W-40 you can find.
