the great oil debate

[kev-yorks]

I\'ve been using Quartz 9000 for about three years now without any problems. If you can get it at the right price then have a word with your engine builder if under warranty if not the choice is yours. As the camp is pretty split some swear by mineral because Mazda say so others do there own thing. I\'m not saying who\'s right but as the Oilman put in one of his posts mineral oil is S**t from the ground and synthetics are engineered in a lab so you pays your money and makes your choice. Set up will also have a bearing on what you use also, if pushing big power then you can exceed the limitations of mineral oil and if running premix with the OMP blanked off then its a bit academic anyway. I\'ll now stand by to be flamed by the mineral oil guys:spank

Well i for one cant make sence of any of the oil arguments but as have every service record from japan from new and they all state the oil that has been used, upon research it was found out to be mineral oil and since import its been treated to the same, with that in mind i had a compresion test at RS4 and came out with 7.2 on the rear and 7.5 on the front, so as has been stated in a previous post "it aint broke SO i aint gonna fix it".

One point is i have a 1992 with 89k miles on the clock with metal gaskets all round so the general opinion was its had a rebuild witch was what i was told when i sent some of my service history to our contact in japan to be interperated.
