Honda Civic Si and Honda Civic SiRThe Honda Civic Sport Package, better known as the Honda Civic Si is a great base vehicle to start a project. Upgraded components on the Honda Civic Si gave this car a advantage from the start. The Honda Civic SiR is the Canadian version for the Si.
Just got my new 2007 civic Si and I'm already thinking about what brand of oil to use after its broken it with the stock oil. What oil do you guys like?? Mobil 1?? Royal Purple?? Amsoil?? Any bad experiences with a higher performance oil?? Ive read some independent oil test results online, but the results conflict with the wide variety of tests they do. I'm in Florida, so despite the fact we do have a winter, it would get near freezing all that much. Thanks for the input.

I use Mobil 1 5W-20 and nothing else. I have 190k on my 7th gen Civic LX and go about 10K between oil changes with no problems. In comparison to other syn oil. I have used Valvoline 5-20 full synthetic and after 6k miles my engine started sounding like there were marbles in it when revved past 5,000 RPM. I switched back to mobil 1 and the problem was instantly solved.

Royal purple FTW!
i love the shit, and i do recommend it for your Si aswell, With either a boosted engine and/or N/A honda engine its a good thing to use synthetic.
Turbo generated alot of heat
Honda engines are generally high RPM cars
so...either way you cant go wrong with Synthetic oils/
This is a thorough a test as I have seen. These guys have nothing to gain (that I know of) from the results. The bottom line is oil longevity, how long do you want to keep the same oil in your engine? Me, I can’t bring myself to keeping it in 5,000 miles! On both my cars 2006 Jeep Commander and my 2K EX I change it every 2,500 miles. The EX get a new filter with each change (usually Fram or Bosch), the Commander gets a new K&N filter every 5,000 miles. I use Castrol GTX 5W-30 in both. I’ve always used this oil and this oil change schedule with these results:
1982 Datsun 310 GX sold at 210,000 miles
1981 VW Sirocco sold at 215,000 miles
1996 Volvo 850 GLT sold at 165,000 miles
1996 Saturn sold at 80,000 miles
1999 Plymouth Voyager Minivan sold at 190,000 miles
None of these cars had any major engine work required. I’m not going to do anything different than what I have done. The only other thing I have done with new engines (the Saturn, Plymouth, Commander and some boat motors we built) is change the oil at 500-mile intervals till they hit 2,000 miles (in the boats we did it for every 1 hr of run time for the first 8 hrs or so). I know people will argue, but metal wear will occur in the beginning.
If you change your oil at 5,000 miles the difference between Mobil 1, Amsoil, Redline, Royal Purple, etc is insignificant. Mobil 1 costs about ½ of what the others do and you can get it anywhere. I would definitely stick with a premium filter (K&N, Wix, Hastings, etc).
Keep in mind these comments are for a daily driver. If I had a car that I raced on a frequent basis, for my own peace of mind I would go with Amsoil, Royal Purple or Redline. Probably more psychological than anything. Well, that’s my long winded 2 Cents.
I would vouch for amsoil all the way. I think it's the best oil out there. It's way expensive, but it is great stuff that is good for up to 35000 miles or one year. That's for very mild driving and I wouldn't keep it in that long unless I drove 150 km's highway every day. I use the 0W30 full synthetic in our van and it's super stuff for wear, fuel mileage, low volatility, etc.
We have a 98 odyssey with 310 000 kms on the clock, with the 2.3 liter vtec, and on a good summer drive it will get 600+ km's on 55 litres of gas. Still runs great too. I did the conversions once: that's well over 30 mpg in a van! Somewhere around 33 mpg or so. The oil is awesome, use their own high mileage filter with the oil too. If you keep it in for long enough it will pay for itself, cause it's about double the cost of most other oils. IF you want to keep the civic for the long haul, spend the money and get top quality oil and air filter.
Wait a minute, the mileage figure I just gave might be too good to be true...my math's not that good. The point is it's very good. It's about 360 miles on 13-14 gallons of gas or so, nothing to shake a stick at in an older van. Your civic would be much better.
