Some Infiniti V6 engines develop increased oil consumption as mileage climbs — burning more oil between changes than they did when new, with no visible leaks and no warning light until levels get low. At Utah's 4,300-foot elevation, engines work slightly harder, which compounds ring and valve seal wear over time. The practical response is checking the oil level between changes and monitoring the rate of consumption. An oil seep appearing at the rear of the engine block near the firewall is a separate issue — a gasket that tends to surface at higher mileages and is easier to address before it becomes a significant leak.

Some Infiniti models use a continuously variable transmission that requires fluid service on a regular schedule — not the extended interval some owners assume from the original documentation. In Utah's mountain driving conditions, the CVT runs hotter climbing highway grades and canyon roads, and degraded fluid accelerates wear. The early symptoms are shudder at light throttle and hesitation before the transmission finds its ratio; late-stage failure is far more expensive. Catalytic converter codes are also common on higher-mileage Infiniti V6 models — we always diagnose before replacing parts, since the code doesn't always mean the converter itself has failed.
