Xr6t Oil Report

[Guest esky]

(Cut and paste from FF.)

Ok have a few things I should point out. I’ve had heaps of these done on my other cars. IMO, its the best $30 you can spend on your car.

Before you read on, check out the report.

I’m not qualified to draw a conclusion on the wear rates in the Barra240 during the run in period. If I was to draw a conclusion, I couldn’t quantify the conclusion with accurate evidence. As I had NFI with the R&D of the motor. Having said that, typically engine surfaces that move relative to each other are separated by an oil film thickness of 3 to 6 micron. Draw your own conclusions.

Maybe someone from ford could enlighten us? But in the mean time…

1) The Acid index. The acidity of the oil increases as heat from engine operation and exhaust gases are absorbed by the oil and causes the oil to oxidise. My result was a 3 on the scale of 1-5. 1 is a typical result from new oil, 5 means its overdue for an oil change. If my XR6T is simular to all XR6Ts, then I would suggest oil changes be made at min 5000km.

2) Oxidation and Nitration. Basically identifies the levels of oxygen and nitrogen in the oil. The greater these levels the greater the degradation of the oil. My levels were OK.

3)Water and Glycol. Water in the oil can come from a number of areas, condensation of the moister in the air when the oil cools down or the coolant system. Glycol is what’s in anti freeze. Water in oil is bad news, as it turns to steam during engine operation and clears the oil away from engine parts, allowing engine wear. My levels were OK.

It appears the engine oil itself did a fine job.

What I can say is, this is the first of many oil analysis. Each time I change the oil. The test was done at 4000km. The 3000km service was done at 4500km. My next change will be at 6500km where I will get another test done. Then I’m doing a five day trip from Sydney to Broken Hill and back. Then I’ll get another analysis done.

whats the benefit of having this done?

Esky, what does the BIG red take action sad face on the report mean? Given your post implys all is OK?

Interesting. I might be blind but I couldn't see a brand or type of oil. I assume this is the oil that is used from the factory?

I was talking to a workshop Tech from BMW only last week about running in and oil and so forth.

I was always under the impression that a new motor will always deposit metal residue into the oil while running in and that a change around the 1500 is the best way to go. As many would know the trend is away from 1500 services and towards service on demand. I was never too sure if this was mainly out of environmental reasons and pressure. Change the oil less and you don't have the waste to deal with.

BMW use a full synthetic, and it would be a Castrol product and don't service the car until 25000kms. The seven Series is out to 30000kms because it is equipped with a device that monitors oil quality. The reason. According to BMW owners that change the oil at the traditional 1500 service had problems with the rings not seating. I have to admit to having a problem with this claim, unless they have an additive in the initial oil. I was always under the impression synthetic was an oil that shouldn't be used to run a motor in. When you look at that report and from what I have learnt from my conversation with MR BMW, the best quality oil on the market is what you want.

BMW dont have a turbo though do they so im surprised ford is expecting 15000km services anyway

[HSE2]

Yes they do but for the purposes of what I have said above the turbo is also irrelevant.
