iteriwarren Posted June 17, 2015 Share Posted June 17, 2015 Getting ready to change the oil for the first time on our own (the garage I bought it at did it for free the first time) and we are confused on the .1 quart. How much is .1 quart or can we just do 5 quarts? Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 17, 2015 Share Posted June 17, 2015 .1 = 1/10 One tenth of a quart. If you look at the side of a 1 quart oil bottle you'll see it is marked with graduations. Usually 9 marks. Sometimes they're numbered. Sometimes there will also be another scale for deciliters as well. How much the car realy takes depends on the car. Some vehicles the stated capacity meets around mid-range on the dipstick. While others the stated capacity will mark it right at the full mark on the dipstick. Subaru tends to be the former, requiring slightly more to bring the level up to the full mark on the stick. The only way to find that out is to start pouring oil in and see just how much it takes to get to the full mark. It says 5.1, so buy 6 quarts, pour in 5 then start the engine and let it run for 20-30 seconds. Turn it off and wait 2-3 minutes and check the oil level on the dipstick. Add oil if necessary. 1 Link to comment Share on other sites More sharing options...
Silent Bob Posted June 17, 2015 Share Posted June 17, 2015 (edited) It says 5.1, so buy 6 quarts, pour in 5 then start the engine and let it run for 20-30 seconds. Turn it off and wait 2-3 minutes and check the oil level on the dipstick. Add oil if necessary. This^ It's more than 5, but not quite 5 1/2 But don't over-fill it. That can cause it to set codes for the variable valve timing. Edited June 17, 2015 by Silent Bob 1 Link to comment Share on other sites More sharing options...
ThosL Posted June 18, 2015 Share Posted June 18, 2015 For the older Subarus it is the least of our worries to over-fill. 1 Link to comment Share on other sites More sharing options...
bratman2 Posted June 19, 2015 Share Posted June 19, 2015 Being .1 is only 3.2 ounces I wouldn't sweat it too much. Truthfully I doubt anyone could tell 3.2 ounces difference on a dipstick. At the same time it is always good to have a little extra oil laying around for top offs down the road. So I would do like FairTax4me suggested. If you only have 5 quarts change it and give it a check. I wouldn't go out of my way for the .1 unless you already have it on hand. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted June 19, 2015 Share Posted June 19, 2015 (edited) man, who doesn't have partial bottles of automobile fluids hanging out in the garage? Edited June 19, 2015 by 1 Lucky Texan Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 19, 2015 Share Posted June 19, 2015 Garage? I keep a part bottle of every fluid my car needs in the trunk. Engine oil, gear oil, antifreeze, ps fluid, and a gallon of water just in case. I also keep a timing kit (no covers, and non-interference engine) and a half dozen different sensors and a couple spare plugs and wires, and assorted sized vacuum hoses, because you just never know. [/thread-jack] Being .1 is only 3.2 ounces I wouldn't sweat it too much. Truthfully I doubt anyone could tell 3.2 ounces difference on a dipstick. Doubtful anyone would notice the difference, but knowing these cars usually need a half quart or so to be added to the engine between oil changes, its good to have that extra quart around.

1 Lucky Texan Posted June 19, 2015 Share Posted June 19, 2015 hah, yeah, I remeber the days when I carried a jug of water to pour on the fuel pump on my 78 (yeah 1978) Honda Civic in summer - sucker vaporlocked regularly after I'd park it. many cars that had spare oil and coolant in the trunk. so far, not required in either subie.
