Just curious why a 2002 RSX has a recommendation of 5w20 and S2000 is 10W30

 

i burned 5w- 30 like rubber

 

I switched to M1 5W30 and have had no (apparent) issues.

Sorry, I don't have any evidence to back up it being better; I just wanted to get my two cents in.

 

Question for s2kforce: Are you going to do an Used Oil Analysis?
That would "prove" a 0W-20 works in a F20C2, well... at least in your F20C2

 

sorry my post was not the easiest thing to read and im not being graded.. sure i should take spend more time and fix all the mistakes and make it more understandable.. but dont read too much into what i type.. hehe

point is

10w-30 put into a car that suppose to take 0w-20 made the car run slow and crappy

according to the link.. the weight should be really close when warmed up and at operating temp

another point is

if a thinner oil (not really thinner according to the link but OK) does make the car increase MPG .. car company's would rec a better weight oil

also do a Used Oil Analysis would really help

i just wanna know if using a thinner oil cause any engine damage .. well more than using the recommending oil

 

Be careful with the hot idle oil pressure!
I have 0W30 in mine and the hot idle oil pressure can drop as low as 14 psi.
Mine is supercharged BTW but I will be going back to 5W30 at the next change to bring the hot idle pressure up a bit.

 

If you think so.

 

If it's hot idle temp, you will need to bump up the 30 SAE to a 40 SAE

5W40? ask in teh FI section, get results from other similar modded users.

 

 

Just curious why you think there's any connection? Last I checked, the RSX doesn't have an F20C/F22C engine.
