do any of you experience a loss of oil?

How much oil do you burn and after how many miles between oil changes?

I lost about a quart of oil after about 6500 miles.
(5w-30 Mobil 1 synthetic)

How about you guys?

 

There's 1/4-1/2 quart in the filter

 

Losing that much oil is normal. Manual even states that.

Dixit

 

whatever came out of the filter went straight into my oil pan.

I appreciate the help guys

 

actually, there have been people saying they are losing a qt every 3K miles and that is still in spec too.. so you are squarely in the middle of consumption.

 

Hey, all you guys outthere with the awesome max's, instead of using coventional oils,try using RED LINE Syn. Oils. They're kinda expensive but it's worth paying the extra for it. I change mine every 10k w/ RED LINE or every 10 months. Give better performance as well. What ever flood your boat, go for it!

 

Redline is okay oil but doesn't really address his situation.

 

When I used Mobil 1 two years ago, I saw mild consumption like you experienced. Since I changed to Amsoil (11/2001) the consumption is hardly noticeable.

If you are willing to spend the $$$ for Redline Oil, do some research about Amsoil. There are members on the board that will sell it to you at a discount.

 

I didn't have a problems with oil consumption. Maybe because I was using RED-LINE when I first bought my car now it's reaching close to 60k
i'm still showing no sign of oil consumption. May it's just me. What do you guys think?

 

I've read some good things about amsoil but I had a question.

Ok, with amsoil your oil change intervals are extended to about 10k miles depending on the type you use but aren't you still required to
change your oil filter every 4-5k miles?

 

yes you are. Oil can last longer if it is clean.

 

i guess you reuse your oil when you change your oil filter, eh... cause i'm pretty dang sure that it'll be a mess trying to keep the oil in the the engine while just changing the oil filter...

 

again, extended drains depend on your driving habits.

you should read the oil sticky first.

get a blackstone..

If you use the Amsoil SDF13, it is supposed to last 6 months or 12,500 miles. I just (personally) hate that tiny go-kart sized filter. I use the Bosch 3323 filter which cost $5.50 (best bang for $$)and has synthetic and paper media inside. I change it every 3-4 months. 2 filter changes in an interval vs. 1 filter change at the same price.

That being said, the Mobil 1 M1-110 is just as good as Amsoil filter, and according to Mobil 1's helpline it will last 6 months/7,500 miles.

I am waiting for the oil analysis for one year's use of regular Amsoil 5w-30, if it comes back poorly, I will try the severe service Amsoil 0W-30 for a year.

 

this is confusing. What I meant, was in order to get longer drain intervals, you must change the oil filter every 3 to 4 k in order to keep the oil running thru the engine clean.

 

I don't use anymore than 1/4 qt between oil changes. The Mobil 1 5w-30 oil is on the 'thin' side relative to viscosity ranges. I would suggest switching to Mobil 1 10w-30 or something like Redline or Amsoil's 5w-30 which both tend to be higher in the viscosity range than Mobil at start-up and operating temperature. Redline is in the middle and Amsoil being the 'thickest' relative to a 5w-30 range. A somewhat higher viscosity within the receoomeded range should help with your oil consumption presuming you don't have any mechanical issues.

 

Nick,


Based upon the oil analysis results for Mobil's "SuperSyn" formulation I've received and come across, I disagree. This stuff simply isn't shearing down (i.e. dropping viscosity) over mileage like Mobil's Tri-Synthetic oil.


I prefer Amsoil because it doesn't shear down AND it is higher in the 30 weight viscosity range than Mobil 1, but the SuperSyn formulation looks like a much improved oil over the previous formulation. Its stablility for a mainstream off the shelf oil is impressive.

 

Yeah I just found out in the other oil thread that the filter can be changed with minimal oil loss from the oil pan... I still think it would be more beneficial, although costly, to change the filter every time the oil is changed.

 

C'mon gang, how costly is it really? I mean on average we collectively spent about $25K on the car itself, spend between $1.50-$1.80 or so a gallon for gas, often spend $150+ EACH per tire, and somehow an oil filter costs too much? Even if you drive 24K miles a year, that is about 8 oil changes...even if you bought $10.00 oil filters, that is $80.00 a year. For around $7.00 a month, I think a couple of forgone Starbucks runs are not a huge sacrifice, particularly in light of how much has already been (and continues to be) spent on the car anyway.

 

Based on info and test results results from the oil forum we both participate in, it appears that the supersyn does have some issues shearing from a 30 weight to a high 20 weight in the 5w-30 formulation but not so in the 10w-30 variety. I also use Amsoil's 5w-30 oil for this reason, its seemingly mosre robust detergent and potective package and that it is a little higher in the viscosity range at both ends to begin with. So, I agree and disagree. If I were going to use Mobil, I would use their 10w-30 or new 0w-30 which has better basestocks and is less prone to shearing down than the 5w-30.

 

Since no one answered your question...

One of the reasons you don't show any consumption is because Redline has one of the lowest volatilities out there. Redline is polyol ester based and that stuff hold up very well at high temperature/high stress applications.

 

Hmmm? I'm like Bill. I haven't seen much evidence of M1 shearing back, unless I'm overlooking something.

The irony of M1 0W30 is that it often labeled a cold weather oil because of its zero winter weight and lower pour point, but it actually carries a higher Kinematic, cSt @ 100°C viscosity too (i.e.: 10.1) than M1 5W30 oil at 9.7. In fact looking at all the tech data of these 2 oils, the 0W30 seems to have a slight edge, even in high temperature environents (better viscosity & comparable flash point), and theoretically, shearing back if that really does occur with these SuperSyn oils, which frankly I wonder about.

 

Yep, the 0w-30 certainly looks good and is their latest formulation which some say is their best (along with their 0w-40). BTW, the only Mobil 1 synthetic I read that occasionally thins or shears down is the 5w-30. The other ones seem to do fine and stay in grade.
