Used Oil Analysis (uoa) In Nsw

[JGTC]

Hi team, has any one used a used oil anaysis service NSW? Looking to get a baseline for metal wear/bearing health before i take on some bolt on mods (turbos, cams, bigger boost).

Motor is staying in the car so i want to do my best to make sure shes good to take on the extra grunt. Will also be doing compression test and other visual inspections.

Cheers

I've used ALS Oilcheck or whatever they're called now. You can probably find my thread in the Wagoneers (nee Stagea) section.

UOA tells you more about how the oil is performing than the condition of the engine. Compression and leakdown tests are what you want for engine condition. Then use the UOA to determine if the oil is protecting the motor ok for the change interval. You can tweak the change interval to suit the oil you use so you dont change it too early or late.

Cheers mate, yeah that is true, it would be interesting to see how the motor is wearing esp the bearings, which without removing the motor is hard to gauge.

Oil analysis is a fantastic tool in the right applications. It actually tells a hell of a lot about engine health. Depending on the contaminants, it can tell what parts are wearing eg Cr, Pb, Al, Cu, Fe, Si etc. Will tell you whether you have wear in rings, bearings, bores, journals, contamination from fuel, coolant, dust etc.

Having said that it's less useful on seldom driven cars - more for fleets of engines running 6000 hours a year. It's normally the trends that they look for, as this tells you more than the raw data.

Another good option is to cut open the filter and examine the wear particles under a microscope (shape, size etc.) You need to know what you're looking at though.
