Has there been any issues with the 2002 and newer 2.4 engines slugging up, I use ams oil synthetic in my car after a 7000 mile break in period. I drove a 86 cressida 426,000 miles using synthetic in the trans rearend motor and power steering with out replacing anything on the car. My 2005 camary is also using ams oil in everything motor,trans, power steering will this cause a problem on the new cars. I also put on a transmission cooler to help the trans last longer as I have all my toyota's. The only thing I am watching is the transmission due to it's special oil type 4 but ams oil say it transmission fluid is supposed to meet this spec ANY ADVICE ON THIS SUBJECT. I also have a 91 lexus with well over 200,000 miles and I also use synthetic oil through out the car so far no problems. I am planning to get a 2008 460 lexus and there they use a special world standard transmission fluid and so far there is no synthetic oils to match it OR IS THERE.
