As I work in formula one I get to be around some of the best of the best, have been talking to the oil and fuel analyzer and was talking engine oils, he has said he only trusts a few brands due to the one he has personally tested.
He is going to be testing a sample of the oil currently in my car which is valvoline v1r, and the. I'll be putting in the Mobil 1 10/60 and doing the same test to see how well the oil copes etc, it's the same test that is done on f1 engines. It tests for 7 types of metals as well so can see what is wearing on the engine, will post the results up when I get them after the Russian race.

Sounds interesting. Would be interesting to read about the outcome.

We gets loads of oil and fuel samples done at work. Every time something big go's wrong warranty want samples. Especially if it's fuel related so they can check for bio fuel or contamination lol

Yeah I was shocked to hear what he had to say about some oils that lots recommend to use! And also very cool to learn all about the viscosity ratings and the temp differences for such viscosity.

Daf are real anal with it last one was a Euro 6 LF that kept bringing on the oil breather system warning as there not allowed to put oil fumes to atmosphere. Turns out cylinder 5 had worn out rings. The trucking was knocked off the air filter housing so it was sucking in dusty air which basically shot blasts the cylinder and rings. The oil sample results even showed metal traces from the valves

Currently waiting for a sample of mine to come back. Changed to Total Quartz 9000 0w30 for the higher HTHS on the last oil change and want to see how it held up after 5k.

Out of interest, what would his opinion be on shell oils?

Is this spectrometric oil analysis? We used to send sample away to get tested when I was in the RAF.

Yeah it is.

He said he would only ever use castrol or Mobil, due to them making their own blends and all from a controlled source that they make the base etc.

Where as others use a bulk buy base then just add stuff to them to make it appear better, as oppose to starting off from a good base and improving it.

hmmm very interesting - my friend who is in the trade said he noticed somthing on new oil delivered to his garage - there was a code on it that showed it was some sort of recycled oil - anyone come across this?

I used castrol 10/60 rs engine oil and it felt like i was always topping the oil up.

how much does it cost to gt a oil sample done and who does it can anyone shed light on this

Bailes1992

Millers Oil Laboratories do it. Cost me £25 but I sent it off nearly 3 weeks ago now and haven't had the analysis back yet.

I started reading the Bob Is The Oil Guy forums and there's some really interesting reads on there. There's so much more than what's on the label that has to be considered when you purchase oil!

You forgot the sump plug.

Thanks, i felt safe with shell and went off Castrol a few years ago, I'm certainly not going to argue with an f1 derived decision.

Shhhhhhiiiiit. I wondered why the engine was noisey.

Bailes1992

Got my analysis back today. It was actually Castrol Edge A5/B5 0w30 oil.

It's actually wanked after just 5,200 miles, how Ford expect the oil to last 12k I have no idea and just proves to myself that it's not in my head when I hear the engine getting noiser after 4,000miles on an oil.

Speaking to Miller Oils the biggest issue is fuel dilution. 2% dilution is 'cautionary' and 4% dilution is 'critical'. That means this oil is borderline at 3%. Not only that the fuel dilution has caused the oil to water down from a SAE 30 at 100°c to an SAE 20.

It's almost certain to me that this is caused by regeneration of the DPF. Anyone who's read any of my posts knows I've had use issues with the EGR calibration on this car which Ford can't fix leaving me with no other option but to remove it once the car is out of warranty. This test now means I will probably end up removing the DPF too for the sake of the engine. Shame.

I am however going to have another test done in 6k to see if that's any better. I am sort of hoping the fuel dilution was maybe due to just one bad regen? I can hope.

thanks buhh. i used to use that castrol magnatec on some cars and the owners used to ask what i had done to it to run so smooth. i used to use rock oil in a 400 single motorcycle i could feel the oil dropping of after 15 hrs running

Interesting that.
