I had a question about synthetic oil. I've been using Mobil 1 0W40 for quite some time now and was told that synthetic is excellent for our engines, but burns faster than regular oil. I change my oil every 7K or 6 months (whichever is first). I got the oil changed 3 mos ago and just checked the oil about a week ago and I was 2 1/2 quarts low. I've checked for leaks, but don't see anything. Is this normal for our trucks to burn 2 1/2 quarts in 3 mos?
In a period of 4000 miles I can use anywhere from 1 to 2 quarts at times man. I see no leaks either. I think it all depends if you really get on the rig man...
I have roughly 53K miles on it. Now, I must admit that I do open the throttle a little on the open road, but I thought 2.5 quarts was a little much too. I'll keep an eye on it, but so far no leaks. I'll have the gaskets checked on the next oil change.
I actually haven't set a time frame to check my catch can. It's usually when I think about it, but when I do empty, it's only a 1/4 to 1/2 full of oil. That maybe in a time frame of 3-6 months.
My uncle asked me that same question. The exhaust is black. I tried to wipe out some of the black soot out. Is it the type of oil that I'm using that burns fast (Mobil 1 0W40)?
Hmmm...seems a bit much. I empty my catch can every oil change 10K km (6K mi) & it's about 3/4 full. I just had my oil changed so now that you've brought this up, I'll have to check how low the oil is before my next one. I have 80K mi on it right now.
In 3 months how many miles have you driven?? Time is irrelevant it doesn't help us gauge the amount of driving you have done. It could be 1 mile or 12,000 miles.
Anyways....
Try stepping up to Mobil 15w50 and see if that helps it subside.
I just checked everything and my last oil change was in April '14 and I started with 51401. I currently have 53941 miles (2540 miles in 3 mos) and burned 2.5 quarts. I'm bad with the knowledge of oil weight, but is 15W50 great for winter here in Pittsburgh?
Same issue here. Been using Mobile 0w40. During the first winter I had to empty the catch can once a week. Otherwise it would fill up and freeze, blowing my valve cover gaskets. Since winter is over Ive checked it and its always empty. Talked to one source, they said try using conventional oi in the winterl. Said synthetic is too slick, not sticking to the cylinders and allowing excessive blowby. Im about a 1-1.5 qts low between oil changes. Ive got around 104,000 miles. Have put about 10k on it in a year.
Same issues here lately. Oil change every 5,000, roll 150 mi a day. 2 quarts low. Motor has some miles on it too, boosted miles at that. ******d everyday, and no puddles. Might try that 15-50. I heard synthetic is just hard to keep in anyways because the molecules are smaller. As the motor gets older and tolerances a little looser, then she starts getting thirsty.
Ok!!?? A building attached to your house with a large door, a shelter if you will for your automobile with a concrete floor. This location show no signs of oil leaks. Wow this app is sensitive today!!
