Any issues with the quality of gas? When we were in Belize the rental car company made a big deal about only using specific gas stations because of fuel quality. I've heard of people removing their cats before heading south because bad gas can foul them up, but I don't know if that's still required. Presumably if you did that you'd throw OBD-II codes until they were reinstalled
Hey linuxgod. I have no experience pumping gas in a LC in Mexico but I have plenty of experience pumping gas in my Honda Civic Hybrid, lol. Three things to keep in mind while pumping gas in Mexico:
1. The only official gasoline available in Mexico is from PEMEX. They are pretty much all over in towns and cities but can be quite scarce on some stretches. For example, there is no working PEMEX station (at least back in February 2015, the last time I was in Baja) between El Rosario and Guerrero Negro. The distance between the two is 372km (231 miles) so it is important to fill up at either terminus of that stretch of road before heading to the next. However, there are private vendors selling gas along the way, especially in Cataviña, a major hub for off road dirt bikers.
2. PEMEX offers 3 types of fuel: Magna, Super, and Diesel. Magna is roughly their version of 87 octane while Super is their version of 91 octane. Diesel is diesel; however, low sulfur diesel is not a Mexican requirement to my knowledge so if you take vehicles that require low sulfur diesel this might cause problems because not all PEMEX stations have low sulfur diesel.
3. There is no self-service in Mexico; all gas pumping is done by employees.
Now, going back specifically to your question linuxgod. I have not detected any real change or difference in the performance of my vehicle when using Mexican gas. Interestingly enough, gas is on the expensive side in Mexico so we can't expect to get good prices like we do, oh let's say, in Texas. One thing to note: the gas service workers really like to top your tank off as much as possible. 99-100 times they are quite friendly and all one needs to make sure is to check the meter is reset to 00.00 and the type of fuel they have. Lots of the workers speak basic English and will offer to clean your windshield, tires, engine bay, etc.
From experience, driving (heck just visiting) in Mexico is an adventure since Mexico is still a developing country. It is the closest thing the US Land Cruiser community has to driving/exploring a non first world area (Cuba is close as well but we have to freight our vehicle there). Life can be quite laid back in the little pueblos but very busy in the cities. The fact that Spanish is the official language adds to the sense of adventure and to the travel/expedition/discovery ambiance. I think Mexico is excellent stomping grounds for the LC 200 and I cannot wait to do so and contribute my adventures/experiences to the community.
