Question about Jaguar Cars & Trucks

1 Answer

Oil consumption my 2003 vanden plas jaquar was consuming oil at about a rate of a quart every two months (maybe 2000 miles). I changed to synthetic and it has lost 2 quarts in a month and I have hardly driven it. Is it fatal - runs perfect and can find no signs of leaks.

Difficult one this ,does it blow out blue smoke ? whats the mileage ? ,need more info to try to work it out as this can be tricky and could be ok ,now with natural oil it could be gummed up piston rings and just using a nice diesel/petrol oil designed for turbo diesel engines might help clean the ring grooves due to its detergent qualities but if this is a high mileage engine then it may be due for a rebuild ,most oil consumption is caused by worn rings/bores or valve guide seals .

SOURCE: Burns through 1 quart of oil every 2000 miles.

After checking out alot of Honda/Acura forums I'm finding that many owners experience the same problem you are having. The best explanation I found was at 2carpros:
From what I'm reading, only way to stop the oil loss is a new engine. If your car is running fine, I'd hesitate to change anything with the engine and stock up on oil.

SOURCE: My 2004 audi A4 consumes oil at a rate of 1 1/2

How many miles/km's you drive in those 3 month's ? oil consumption is normal ! Check when you first start the engine in the morning wetter or not you see a puff of blue smoke, if you see smoke , your valve seals are leaking.
1 liter oil each 2000km is normal.

SOURCE: 2006 Chrysler Minivan - oil consumption - time is running out

I do not believe there is a fix by Chrysler. My van has 50000 and seems oil consumption is getting worse. It is either past the valve seals or the piston oil control ring. I believe Chrysler KNOWS ALL ABOUT THIS! If you google search this there are to many complaints! 1 quart every 3 thousand miles is not exceptable unless you are driving a model T!

Using 1 quart a mth. no visible leakage. i can tell when it starts getting low by how it runs. live in mx. 110 /87% humidity. is this normal usage? i never had to put in extra oil and get it changed every...

One quart per month is a bit more than I'd expect but you didn't mention how many miles you drive during that month.If you live where the ambient temps are very warm, it may help to use a good synthetic. Synthetic oils do not burn off or break down chemically as fast as conventional oils do. I'd use a 20w40 grade.
Depending on the miles you've driven you shouldn't have excessive ring wear but the valve stem seals may have dried out and cracked. If the usage remains constant and there is no smoking etc, you could either leave it alone or have new seals installed.
Average driving is approximately 1,000 miles per month so when figuring consumption, use that as a baseline. One quart per 1,000 miles in very hot conditions is a bit high....I'd expect to see 1/2 qt or slightly less. One odd thing though is that generally, especially in an engine that holds six quarts to begin with, at five quarts, the engine should not feel any different!!! use miles to determine oil change intervals. Oil is best changed at between 3K and 4K miles. Only way you use the 3month method is if you don't use it much. (you can run most good synthetics longer than that)

2003 Passat GLX V6 4motion with 194K km. Requires 1L of oil every 4-5000 km. Is this normal?

That consumption is great, no worries.
Most healthy cars will consume a quart in 2,400 to 3,00 KM.

Car manufacturers will not repair and consider a quart in 965 km to be normal, I would be livid at that consumption.

If consumption gets too much, consider a high mileage blend, like Casteroil. It is a semi synthetic, and actually does lower consumption.

There is actually nothing that you could do to lower your consumption, but keep everything clean and maintained.

The problem is that the last 4 times that i make the oil change always i have to add some oil before the 3000 miles but i cant see any oil in the concret outside, but i saw some oil aroud the motor seal...

You almost never see smoke, since catylic converters. A quart at around the 2000 mile mark is considered excelent, so I believe that you do not have an issue.

Still, it would be nice to burn zero oil, certainly my preference, but that is not how it goes. Most manufacturers would not repair a new car unless it burned MORE than a quart in 600 miles. I would not be happy at all about that.....

One thing to consider it Caster oil High Mileage blend. It is semi synthetic, and has polymers that help seals and consumption. I really like partial synthetic... I have witnessed measured improvement on several vehicles that had consumption issues.

Burning a lot of oil

A quart every 1000 miles is not unusual, but can get expensive if you are using synthetic oil. Have you always used that in this Jeep? Even though synthetic oil is of higher lubricating quality than conventional oil, it is still thinner, or has less viscousity than normal oil too. What this often means is that an older engine with slightly worn valve seals or some engine wear might consume more oil when you use synthetic. This is not a problem, really, as long as you keep tabs on your oil level.

If you want to experiment around, once it gets warmer out, you could try some 20w-50 oil and see if your oil consumption drops, or even try adding some Lucas Oil stabilizer to your next oil change. If this helps you know that part of your consumption is due to the thinner oil you were using.

2006 Magnum Oil Consumption

First off how many miles does the vehicle have. Also what oil are you using. If its only a quart between changes then I wouldn't worry about it. If your using synthetic you may want to consider Amsoil. Its the best there is in the world.

Using to much oil a 2002 accent with 76k. uses about a quart every 1k miles. dop i need to adjust the valves?

That's within acceptable limits according to Hyundai Motor America's standard: For a proper diagnosis, the amount of oil consumed over a known mileage should be checked three times and then averaged.The accumulated mileage divided by the total amount of oil added will give the consumption rate in miles per quart. If the oil consumption rate is greater than 1 quart per each 1000 miles, further diagnosis may be required.

Can you use a full synthetic oil in 93 Dodge B250 Conversion van

Yes. Providing the engine has been well maintained and does not have lots lof sludge in it. I do not recommend flush (it loosens up too much debris all at one time and can plug pump screen. On older engines i usually introduce synthetic in "stages", replacing two quarts on first oil change, then 100% at 3000 miles (with filter). Does it work?? I used synthetic (amsoil) in a 318 engine bought at 100k miles and ran it till the trans finally started slipping @ 363K miles. When I bought it it had some light lifter noise. After using synthetic for a few months, noise disappeared and I never had any internal problems for the remainder of the time I had it (and sold car for $400 just for the engine!!!) As far as seaks go, usually synthetics will soften hard seals and lessen leaks valve covers etc may leak more but usually are easy to replace. Good luck PS: only synthetic I would not use is Mobil because there are more additive packages and less actual lubricant in each quart than you could imagine: it has been "re-formulated" at least ten times since they first put it on the market.
