Originally posted by TheMAN How can "oil is oil"?

If oil is oil, then I suppose I could pour in crude oil, or transmission oil, or WD-40, or gasoline, hell why not put in diesel? They're all in the petroleum group! Oil is oil right? Riiight. Screw the scientific data,which is marketing BS-study it and select your oil according to it. I will grab 4 liter jug with my eyes closed of the shelf and have same results and same engine life as "scientifically backed" oil data user. Don't be anal, do I need to list all API labels for "oil is oil" phrase? Alex |

The Man is right! </butting in> |
Back in the olden days of the Protege (1991), Mazda recommended an oil change at 600 miles. I guess they don't now.
I did one according to the recommendation and it didn't appear to hurt the car yet, ten years down and counting. Today some manufacturers (e.g. BMW) ship their new cars with Mobil 1 and recommend the first oil change after 15,000 miles or a year. This seems long to me, even for a synthetic. I feel guilty even with Mobil 1, after 7500 miles. On the other hand Mazda, for some reason, recommended against using full synthetics in the first generation Miata. It appears that manufacturers have a diversity of opinions about oil and that these opinions change over time. |
woa, this discussion is turning into a heated debate, haha. I dont care, im gonna be a conformist and be a "victim of society" and just buy some mobil 1 and change it every 3k or 4k, proly 3k. Im at 2300 right now on my P5. heh

How will you be a conformist when the manual recommends every 5,000 in 'harsh' conditions or 7,500 under mild conditions?
