non lab analysis of my new oil
Non technical analysis
( probably Not safe for techies )
Changed to Mobil 10w60 extended life Motorsport oil.
About 1500 miles into this oil (halfway ish for me, I change regularly, oil! Is cheap, I only do 8k per year anyway).
Noticeable difference in sound, noisy when cold, first minute or so, almost silent when warm, smoother than ever.
Low down pull has improved, feels like its been tuned a bit, but nothing changed other than oil.
My standing still oil temp worries (after high speed motorway runs straight into standing traffic) have almost completely gone.
Temp wise, it takes a lot longer for the engine to show any signs of anything other than normal (oil and water ) with this oil, maybe an extra 20 mins of traffic jam on a hot day before the oil hits 98 \ 100, but, the engine stays hot for a long time one there.
Went to oulton park and did a track day last week, mild cold day but not freezing,
oil temps where fine, lower than previous oils on track days by around 5 - 10 deg c,
although again, once it was hot a slows paced lap didn't cool it much at all, its as if the thicker oil is more deeply heated ( I did say this was a non tech analysis).
Having looked at bits of video, I can see that I was using 6400 in 2nd and 3rd quite often, which I limited on previous track day outings (6000) to keep temps down a bit, so that's progress.
Consumption wise, just topped up by 200ml, now at 2100 miles in, two green lights out on my dash.
Did not need to top up once on the track day.
I like this oil :-)
Was using fuchs silklolene pro s 10/40 Before
