Thread: Got my oil test results

Cant help you with the oil report.
But what does the oil testing cost?

doh

The joys of oil sampling...Is this your first oil sample or have you got a few to compare..
You say you got the injector seals/washers replaced, was this because you had fuel dilution previously?

I wont bore you with some of the weird samples we return..fuel dilution is 1 that comes and goes quite often
Change the oil and filter and resample after same km's would be my suggestion, or run it another 1000kms and see if it has increased, bad fuel dilution will be noticable by raised oil level on dip stick.

Hope you dont have to many sleepless nights till your next sample..

Yep - X2
Dump oil & filters and replace with new. Monitor oil level for an additional 1000K+ before sending for a test. As Ean points out - no 2 engine oil tests are the same and as a former fleet manager, I've seen some weird and wonderful results
If only minimal change downwards, save your money and don't test (Obviously)
Any further increase of over 5% (450ML) is worthy of deeper investigation as that is approaching 1/2 a litre of total volume.

Don't know your driving conditions...Stop start city grand prix?? - short commute with engine not reaching operating temp?? or long distance country driving but in my opinion (And not wanting to open a pandora's box of oil preference) - 5W30 Edge may be a bit light even though it is a quality oil.

Good luck!

Looks like Td5's have a habit of this (fuel dilution) and apparently the later spec ones with the higher injection pressures are more prone (doh !)

IMO 4.4% is miles too high, in an ideal world you want under 0.5% but no lab in Oz that I'm aware of lists anything under 1%.

I'd use a 15W40 CI-4/CI-4+ or CJ-4 HDEO just for short term testing.
It's much cheaper than Edge or M1, and the xW-40 will tolerate the dilution a little better due to the better viscosity retention and better additive package than the 5W-30 while you try and get on top of it.

As Catmatt said, driving conditions contribute strongly to this too. Stop/start/short trips don't allow an engine to really get components and oil to operating temps and volatilise off any moisture and fuel that can get past the rings.

The blotter test as discussed on another thread can help keep on top of this too.

BTW, which lab are you using ?

<edit> as the other fella's said, dump it and re-test, but I'd give at least 3000km, maybe more. Fuel dilution from a one off test is an obvious issue, but anything else needs trending over multiple tests.

Silicon can be part of the oils additive package, it's used as an anti-foam, to know whether it's dust ingress (silicon oxide) you need to read it with some other contaminants and I don't find the labs very good at interpreting results either.
Having said that TD5's are known for poor sealing of the air filter and air box on occasion, so it's worth checking the panel on how well it's sealing.

Thanks for the quick reply Ean. Yes it was my first oil sample. I have suspected fuel dilution, or I have just put in more oil than was necessary which I have been guilty of in the past. The level has not changed on the dipstick at all. I hope they spilled a bit of fuel when they did the injectors. So I will do a change and get the oil re tested after 1000k's or so.

Lets hope that was the case...Oil sampling is good, but its hard to determine alot from 1 sample..I have seen alot of sleep lost because of bad samples only to find the next ones are fine..(mainly my sleep)
