Hi guys, i have own my rover for 4 years now. I always put 87 in my tank. Should i try a higher grade sometimes? Can 87 grade affect my rover. I was just wondering because i saw on the forum were some guys are using a higher grade on their rovers.I have 124,000 now and it rides pretty good so far with the 87 grade. Starts up fine everytime i fire it up in morning. I want to know will the higher grade give me better performance,and longer life on my engine. One more thing. I will be replaceing my rad and need to get my a/c condensers fans replace to. Does anyone no were i can get reasonable fans for a good price. Atlantic British is about 300.00 a fan. Why are they so munch a peice? Any feed-back guys Thanks!!!!! 99 disco 1 SD 124,000
