Engine oil guru's - i have a question for you

[cheapdouchebag]

I am looking to change my engine oil soon in my accord euro cl9, thing is i dont know what oil should i be using. wait let me correct that, i want to know what is the current best oil on the market.

money is not an issue, all i simply want is the best for my car. to me, it made sense when i had a vti eg sedan to put whatever works like castrol magnatec, but now i am looking for the top of the range because it doesnt make sense to me that i have had such a huge upgrade and only put 'fine' or 'bang for buck'.

im currently contemplating on either using Mobil 1, royal purple, motul or martini racing.
what is your suggestion? im undergoing research as we speak as well.

help is greatly appreciated
thanks

Theres plenty of threads regarding which oil is best, there are even proven videos on youtube.

So far - Nulon seems to be making the most peak preformance, compared with Royal Purple, Mobil 1, Motul etc.

Good luck,

Didn't realise oil choice makes more performance ? Unless you drastically alter the viscosity rating from OEM range , or opposite from ambient tempreture range !

Point is OEM FEO is recommended for all hondas. Try the new 5-30 Honda ultra for synthetic.

We had a short discussion on this in DC2-PWR's build thread. Nulon was best for power output according to Rigoli, although he doesn't discuss engine protection. DC2-PWR's source states that Royal Purple Racing 51 is the best for engine protection, although there are some limitations in their test.

i do understand FEO is specifically forumlated for honda engines, although also i belive my driving style at times maybe be too excessive for the oil to protect my engine as i can be very harsh at times.

i hope im not making the illusion that i am after power from oil, i am looking for maximum protection for whatever i put it through because this car will pretty much see every condition available in australia.
im not too fond of the FEO ultra so far, service was done with that oil by astoria honda at the km interval at 83xxx kms and now it sits on 86xxx kms and i feel it should be running more sound than should be. I mean my idle revs are sitting at 900rpm, should it be lower without adjusting any valves?

i have been watching demonstration videos of leading motor oil brands, but i was hoping someone would give me insight on their own experiences with motor oil in honda engines.

[bennjamin]

personally used FEO on a few different hondas for many years - around town cars and also high revving track engines ( B18c7 type R , K20a type R) and all good. Just more frequent the change intervals as FEO is a mineral oil and will break down faster than a full synthetic.
As for your car - it idling at 900rpm sounds another issue rather than chosen oil. Idle is dictated by the ECU and the FITV or ICAV not engine oil. PS I use honda ultra in my current K20a and no issue.The only real advanced conditions of Australia vs the rest of the world , are higher heat on average.

You are not some race car driver and the thrashing you can do isnt that different from anyone else here - in extreme conditions the oil and filter change more frequently.
If you are paranoid - consider a 5-40w engine oil such as castrol edge 5-40.

I agree with Ben.

You won't notice a difference with any brand of oil on the street, even the cheap shit oils will lubricate just fine. You can run sythentic forever if you just simply replace the additives that break down over time (the "5000km" changeover point) - but most people don't see the additives breaking down as the issue, its always the oil.

If you are as anal as you are, why don't you speak to honda, ask them what oil pressure is required for the engine at a certain RPM and go find the oil viscosity that gives you that oil pressure at that RPM?

Oh and regarding what oil gives more power..haha, can't beleive rigoli actually agreed to perform such a test.. seriously.

Why? What is your opinion on the test performed?

[Chr1s]

It's a load of arse.

Yes I gathered that was how you felt about it, but can you please explain why? I'm interested to know why you feel this way about the test. You speak like you know Rigoli on a personal level and although I'm sure there's more to an oil than the power it produces it would be nice to get some more understanding from your experience.

[Chr1s]

I don't know Rigoli from a bar of soap but apparently he runs a first class workshop.

Oil is not there to give you power, it is there to lubricate your internals. Every single time you see someone claiming they made more power with another brand of oil, its another marketing ploy. If the oils have the same viscosity that is.

First of all, how can a chassis dynamometer have the resolution to be able to detect a difference in power through engine oil alone, there is WAY too many variables you cannot control to be consistant enough. Check out the fan in the video when he runs the nulon test. Not saying thats the reason, but why is it closer than the others?

At university we've performed a test similiar on the FSAE 600RR engine, using motul ester based oil and mobil one, absolutely NO difference, thats using an engine dyno picking up from the output shaft with minimal losses to worry about. But apparently in the bike world, motul is teh shiznits.

Sorry if I sound like a dingus, but i'm a scientist and our tests are all about accuracy, precision and consistancy, what good is a test if you're measuring it with the wrong tool? - "Good enough" doesn't cut it.

So now, my comment aimed at Rigoli, is why did he bother to tarnish his technical ability by taking on such a test that is utter crap? To most car enthusiasts who read a magazine and can't tell the difference between a piston and dog shit, it's "educational"

/rant.

Great posts there Chris.

A summary is that any person or business that partakes on a oil test - does
So with benefits. Be it monetary or sponsorship etc from said oil companies ( elf and royal purple are prime culprits!)
