...... and I have some interesting car bits on order 

Nice stubby spanner set and a few more tool items I've forgotten about.

The most interesting though.....

An oil analysis kit from me ma and pa (well, I will have to physically buy it myself  )

Anyway I've wanted one for ages. I remember a discussion in my 0-60 thread where a few of us thought that a 16 year old omega could have power sapping engine wear. Others thought that they wouldn't have wear at all assuming regular oil changes adhered to.

Compression tests so far seem to show there's no compression loss. However doing my cam cover gaskets in the garage one of the lads commented that my cams were f****d  . That was a bit excessive in my opinion but they were definitely scored and lobes seem to have wear.

No idea what the results will be. Will post up results when I get the report. Can't wait

Are you cutting open the filter and examining what you(don't) find inside? How many tests will your kit provide, as you need a few to get a picture of what's happening to the oil.


I bet you find that if your changing the oil within the interval, there's absolutely nothing to worry about.

Happy 40th birthday for tomorrow, Mr Bear.

No mate. Dropping the oil and sending a sample to the oil lab! For around 40 notes they test the sample and find microscopic particles of various metals. They then give a breakdown of what the particles have likely come from and thus a good wear-barometer.

As said I don't know what they'll find. That's the fun

I'll be 34 opti  but thanks!

Just to add...

My intrigue has always been my engine in comparison with a box fresh omega engine. My own personal feeling is that even minute wear in engine components like cams, lifters, bearings etc add up to a drop in performance over all those years.

That being why some people reckon cars lose approx 5 horses a year.

ahh .. the good old SOAP tests .. takes me back a few years collecting samples for those, eventually the RAF stopped wasting spending money on them because they proved nothing, if oil changes done on time..

Yeah that's pretty much the tests that'll be done.

They tried, selling these around the road haulage industry few years back, they were, being offered by shell and BP, the big boys like Tesco and bower(McDonalds) tried it, The out come, changed to fully synthetic and extended service intervals, oil was found to being under-used and could still carry on for more km's.

I think I can understand what you mean.....

To get a true gauge of wear you'd have to check the oil from day one to 16 years later for example. However if that was the case the engine would be worn cos the oil hadn't been changed. 

I suppose on the other hand though, it will be interesting to see if there's any wear metals in the oil

Oil in aircraft engines is changed very frequently .. measured in flight hours not miles travelled. We used to have to take SOAP samples every 50 hours and change the magnetic chip detectors - 3 per engine - (basically a bolt with a magnet on the end that screwed into an oilway), place them in protective cardboard sleeves along with the little bottle of oil and return them to base at the end of a trip. On a Far East rotation we might fly some 250 hours, so we'd get back with a whole pile of boxes to be sent away for analysis, by the time the results came back the oil had all been changed anyway !!

Right got ya nige. But at least it would show abnormal wear though right? Thus a good indication of what part was likely needing replacement (albeit that safety being more paramount 50k feet up lol

Happy Birthday Webby!

Happy Birthday! Also fascinating to read about the more servicing methods of the RAF, Entwood
