Need some advice from the oil experts.
I bought this 2000 Civic Si new and now have 60,000 miles on it. The stock engine is 1.6 liter and produces 160 hp at 7,800 rpm. Redline is 8,000 rpm. Car is driven only on 50 mile trips (each way) to work. This is over twisty, hilly backroads which involve a lot of shifting but almost no stopping. I regulary rev the car to the 7,000 to 8,000 rpm area, and on a daily basis it reaches 80 to 90 mph at least for short intervals.
Honda recommends 5W30, but says if temp is over 20 deg. F, is ok to use 10W30. I do want to stick with a 5WX for cold weather here in NW PA.
To date, I have always changed the oil with Pennzoil 5W30 at 7,500 miles. The oil might be down a little when I changed it, maybe up to 1/2 quart, more or less.
Last oil change, I switched to Mobil 1 5W30. At 4,000 miles, I just added 1/2 quart to top it off.
I know this is not a real high consumption rate, but I am considering how to proceed. Note I am willing to deviate from Honda's recommendations on grade if there is a benefit. (Looking at the Civic Si boards, Mobil 1 is commonly reported to have high consumption rates on these high reving engines, but they dont know didly about oil over there.) Should I:
1) Keep using the Mobil 1 5W30, just add as needeed?
2) Go to Mobil 1 0W40?
3) Go to Delvac 1 5W40?
4) Go back to Pennzoil (or another) dino oil?
5) Try something else? I prefer something that is readily available locally...not the Amsoil, Redline or Royal Purple, etc.
