A TL owner from the Acurazine forum asked me to post these questions for him.
The car is a 2004 Acura TL used primarily for commuting in the San Francisco Bay area, where stop-n-go driving probably makes up at least 25% of the miles. The vehicle is equipped with an onboard computer that determines oil change intervals, and for this car and the particular driving style, notifies the owner for an oil/filter change every 6500-7000 miles, which tells me that the car sees very little city driving besides the stop-n-go highway commute.
The owner is trying to save some money on oils, and has narrowed his choices down to either the Havoline or the Supertech. (BTW, is Supertech avaliable in 5w-20?) If the Supertech oil combined with a Supertech Oil Filter is used at 4K drains, the total cost over a 60K period is about $103. If the Havoline oil combined with the Supertech oil filter is used at 5K drains over a 60K period, the cost is about $109.
Disregarding cost for a second here, what is the maximum interval that you should run Supertech motor oil/Supertech oil filter given those driving conditions, if the owner does NOT plan to do an oil analysis? Same for the Havoline motor oil/Supertech filter combo, what is the maximum interval that you should run the oil/filter given those driving conditions if the owner does NOT plan on performing an oil analysis?
Thanks in advance for any and all comments.
