I stopped by my Honda dealer to pick up some oil, intending to follow recommendations on this board and the owner's manual... the Honda parts dept said Honda has just started recommending 5W20 oil... I asked specifically about the S-2000 and the rep indicated yes, it applies to S-2000's.

Has anyone else heard this? I'm at about 700 miles and bought some oil just in case (so far I'm still full up).

 

NO!....do not use 5W20 in your S2000. Return it. 5W20 is the oil now being used in alot of the new Hondas that have ULEV certification. This does not apply to the S2000. The S2000 you MUST use 10W30 and nothing else. 5W20 will provide excellent protection and fuel economy for vehicles like the Civic and Accord but not reccomended for the S2000..


Why go to the dealer for oil when you can go to your local parts store? Just pick up some Valvoline or Castrol 10W30....Make sure its a Conventinal oil and not a synthetic..

Good Luck

 

Thanks - on both counts... first, I'm making sure this misinformation is stopped at the source - the service dept. is going to "educate" the parts dept. (buying oil at the Honda dealership was an impulse / convenience purchase). The service dept. said exactly what you said - do NOT use 5W20... use 10W30 only. They also said (and this is inconsistent with advice on the board) that synthetic oils should never be used.

Second, I'm going to return the oil (which has not touched the car - and wouldn't without checking first with this excellent source of information) and go to a non-Honda source for what I really needed in the first place :-)

 

Dont ever listen to the parts people
last time i was at the dealership looking for Honda Oil(just cuz i can feel safe) rather than using Mobil, the guy told me that Honda and Castrol is the same company. I think and knew he told me that because he was out of the Honda oil....Can you believe that?????

Honda is Mobil at least in the usa.

 

I'd like to know if using 5W30 during the coldest winter months is a good idea. Also, does 75W90 work better in the transmission than 80W90 or 90 for those who see below freezing temps?

 

I believe 5W-30 is just something the EPA foisted off on the car companies and car owners for lower emissions during startup.

I'm convinced that 10W-30 stays on bearing surfaces longer after shutdown (so is still there to do its job during startup) and provides a tougher oil film than does the thinner oil. So it's at the expense of a minute increase in fuel consumption - that's a worthwhile trade for me.

By the way, I'm not a lubrication engineer, but I am a mechanical engineer with 30+ years of jet engine design experience.

 

I was told to always trust a rocket scientist!

 

Did your dealer give an explanation to why he recommended not using synthetic?
