I drove my 2007 IS250 RWD from California to Virginia. Got my car used, got a change oil and waxing done at Lexus before I left, had 80% tread left on tires and did not get the carbon buildup issue/symptoms before the trip. Anyway I'm listing down some tips and experiences I had before and after the drive.
-Only mods I have are F-sport exhaust and intake.
-Total Miles driven: 2832 miles
-Took me 3 days to get to VA, my job gave me 8 days to get there, so the remaining 5 days were free.
-drank 10 redbulls in those 3 days to keep me awake.
-had 32 quaker granola bars too suppress hunger and control my digestive system to not go number 2. I didn't poop til I got to VA.
-I dorve through 8 states(CA,AZ,NM,TX,OK,AR,TN,VA)
-Slept in my car 2 times to save money (lol I know I'm cheap but not cheap on my car)
-I only put 91+ octane gasoline on my car, some gas stations after Texas had 93 and I bought that.
-1 full tank of gas could go 392-425miles, I averaged 25mpg
-I used clear track tape on my bumper to protect it from bugs and rocks but I didnt cover the whole hood cause I got lazy. I got a a couple rock chips on my hood and I saw 2 pieces of flood fly off a truck but those scratches can be buffed our
-Gas is way cheaper here in VA, The price of VA premium gas is the same as regular gas in CA.
-I took the I-40 for the majority of my trip.
-CA=had a good driving scene through deserts and twisty highways
-AZ= same thing with arizona and I stopped twice there I noticed most of the girls there were fit.
-NM= had nice driving roads except when it got dark it was a straight boring highway. I had to turn my blue interior LEDs on and blast the music.
-TX=Well I've been to texas before but it wasnt very pleasant this time cause I rained the whole time through texas.
-OK=Im not judging the state if anyone lives here. The roads were boring and the weather was bad, strong winds and rain the whole time.
-AR=Weather got better but everyone was staring at me when I pulled up to gas stations. wasn't a problem.(im asian and im friendly) Until they saw my CA license plates and found out im in the military they were nicer and smiling LOL!
-TN=Maybe the best state I drove through. Roads were like beautiful through forests and hills. weather was nice. I gassed up at some back country gas stations and everyone was nice. cash register was nice too and after I paid they saw my plates and asked where in california and when I said I was in the military they were even nicer.
-VA= most of the roads on the TN/VA border have potholes. I'm glad I didnt lower my car.
-I have the F-sport exhaust and intake. they are only 4 months old. In CA my drive to work was only 5-10 mins. After driving to VA, I noticed My IS250 has a louder rumble at idle and at WOT. I know this exhaust is a muffled left muffler and a straight pipe right muffler so I don't know what happened but it sounds better.
-Never had the carbon issue before. but my car had the symptoms twice first in Arizona then in Texas. It was my first stop for gas and food. When I approached the stop light i felt the rough idle, so I threw it in Neutral. I drove with S-Mode on to make overtaking fun. After keeping it in neutral for a few seconds it went away. The same thing happened in Texas and didn't happen again. It wasn't much of a problem cause I was expecting it to happen from reading on the forums and throwing it in neutral made it idle normally. after driving 1 weeke in VA, I haven't experienced the carbon issue and I still love this car.
Here are some pics I took, I don't have a fancy camera.
