just a quick questions. How long should i go after running a fuel system cleaner (redline si1) before changing the oil. Im going on a road trip (1800 miles all highway) and was planning on dumping a bottle of redline si1 at the start of my road trip then at the end of it changing out the oil. I know most people suggest changing the oil right after you run any fuel system cleaner full tank of gas, im going to be filling up my tank at least 4 times on this trip. is it safe for the oil to run the fuel system cleaner for 3 more gas refills or should i run my redline si1 midway through my trip? Thanks
