My posting was in response to the reply that seemed to indicate mechanics would be working for free if only the marginal increase in the cost of synthetic, including the cost of extra labor involved with bottled, rather than bulk, oil were added to the cost of the basic oil change. There is not much, if any, additional labor involved.
I agree that businesses are free to charge what the market will bear, and it is up to the consumer to decide whether to pay for it. I meant to say the marginal price of the change would only increase by $24.00 to the business; not that the price should only go up by $24.00. Higher cost items such as SUVs have a greater profit margin than econoboxes, as well as other examples given here.
Forums like this can help consumers decide the value of premium products vs. cost. Many would be better off changing their oil 2.33 times as often with dino, if the cost of syn is $70 vs $30 for dino. A leading analyzer finds little difference between UOAs for syn vs dino. I have junked 3 high mileage/hours vehicles run 98% on dino, none due to oil related problems.
Changing the oil yourself brings syn changes a lot closer to the cost of dino changes. In sum, I agree with most of the postings.
benjamming, have read many of your posts, and always enjoy them.
