Congrats on the P5 finish...I'll take those all day long.
As for the oil, this is always a fun conversation. There are folks in both camps (yes it does/no it doesn't) so the best advice, IMHO, is to change the oil and take it out of the equation. 👍
EDIT
Wash the car while you're there, too... 😁
Don't forget the sticker, which says-this sticker adds +10 bhp-
Knowing gran turismo since being a child, i am sure the oil change "still" improves performance.
In one GT edición, when you bought a new car and went to the workshop for an oil change, without the car ever seeing tarmac, it gained something like 10-20bhp.
I raced B and C.
I would have enjoyed race C more. But in B lobby i am not competitive in spa. First race, lap 1 because of giving way to a faster one, i touched 1mm of curb, spin onto grass and downhill. Chasing the field for 19 laps. Worst - whenever i came close to someone, they quit the game 😢
Race B - 1,38.001
WRX, not a good time either, i dropped to DR C, but i kept my sR S all the time.
AND, even though I'm not fast on both tracks, my second Spa race looked awesome in rain, the puddles, the spraywater from the tyres, reflections in puddles. This was so cool 👌. And race B, yeah, it is a given, that it's a rough race, but it's definitely not a meta race, my last 5 races, had maybe 4 evos, the field completely mixed, i like that. Oh, and i got into a unfortunate line on the last two right handers, needed to break a bit before last corner, a lancer crashes into my back, i got immediately a3sec. Penalty, i swear on my little doggy, he was also upset about it.
