Hi All. I now live in Las Vegas where the the temperature runs over
100 degrees regularly. I used to live in Chicago.Should I switch to 10w30 ? I currently use synthetic 5w30.
Should I change the radiator coolant to a different mix?
What else do you recommend I do to the car to help it perform in the
110 degree weather.Also, the car is burning almost twice as much gas as it did in chicago. I attribute this to the AC running all the time. Is there somethingI can do to keep the car from burning so much gas?
Thanks very much. No need to switch to 10w30 oil what your currently using is very good to start with. as far as the coollant is concerned if its been more than 2 years since you last flushed the coolling system do it now! using a 50/50 mix. living in that kind of hot enviroment for an automatic transmission is a killer for it hard on the tranny oil pretty
much cooks it in no time heat kills automatic trannys! highly recommend a transmission cooller for your lexes thats a wise investment. your fuel mileage may indicate a problem remember your A/C is constantly on dont no your driving habits but check your tire pressures should be generally around 30psi or it could be that "Las Vegas heat wave drying up your gas!" =D haha
