Hey guys i currently use 10w30 Royal Purple and i wanna switch oil on my turbo gsr. Whats the best oil for boosted honda b series. What do you guys use? i think after doing research, im gonna run 15w50 on my next oil change.

 

i was curious about this also. I just put Mobil 1 15W-50 in today for the first time, and my oil pressure is definitely better than it has ever been before.

 

My buddy asked Geoff at Full-race this question, and Geoff said to run 20w 50 VR1.

I have always read when using multi-viscosity oils its best to keep the range as close as possible for your operating temps. 20w-50 would be better than 15w-50 as long as the temperature allows for 20w

 

funny i just posted a question about oil weights... really was refering to my oil consumption but this is still interesting.

 

this hot weather has gotten my oil pressure running funny..... what kinda psi are you guys getting after the car is really hot?

 

i gotta get an oil pressure gauge

 

My oil pressure has gotten low at idle with this damn heat.
Lowest is like 12-13 psi. I know 10 is the minimum.
D15 btw.
Im using 10-30 as always.

 

Im in the same boat 35psi at 3500 d6y8 5w-30

 

i ran mobil 1 15w-50 when my b18b was boosted and it ran like crap. switched to mobil 1 10w-30 and it ran much better. just my experience though...my friend with a boosted b16a is running the 15w-50 and it runs like a champ.

 

hondas have tight clearances....they require a thiner oil to get into those tight clearances.

a higher guage pressure isnt nessesarly good, it simply means more restriction for oil and and reduced flow
