Oil for 306 1.8i 16v

[306 xpto]

Sorry for typing in English, but my French is not so good.

I'm from Portugal and i have a 10W40 Shell oil semi-synthetic.

Should i put a 100% synthetic oil?

PS:

When i finish a 10 km mountain of heavy acceleration, i can hear too loud the valves working. It seems that the oil don't comes till te top of my motor.

Is it normal?

hello

I can't help you for mecanic but I can try to translate to enable mecanic men not speaking english to help...

"306xpto utilise de l'huile shell semi-synthèse 10W40
la question est : doit-il utiliser de la 100% synthèse ?

PS : après une dizaine de kms en montagne avec de fortes accélérations, il entend fort les soupapes (je crois) qui travaillent. il semble que l'huile en vienne pas jusque au haut de son moteur.

et il demande si c'est normal ? "

En général la 100% synthèse est préconisée pour les moteurs à haut rendements ou turbo compressés, pour une 1.8 16v je pense pas ke ca devrait poser pb.

My english isn't so good, but i hope it will be ok

So, 100% synthetic oil is way better than half synthetic. With 100 % synthetic, i'm able to do a bit more kilometers with a full tank, about 2-3 % more. I usually use 5w40 or 0w50, wherever is avaible at my local store. Plus, your engine will wear less quickly (better
lubrication).

About your valves, i'm able to listen them a bit more after heavy driving, but not that louder than normal use. I think it's normal, but someone will confirm this.

Anyway, what's your engine type ?

Merci phil306!!
Thks for the tradution.

So, do you think that the extra valve noise after a moutain road have something to do with the malfuncion of the oil pump? or type of oil?
