Just bought 2002 X Trail - using oil


2002 X TRAIL T30 ST How much oil should my X Trail be using? I admit that I'm not knowledgeable. I'm still trying to pin down the amount, but it seems to be using a pint or half a litre every few hundred kilometres, and I'm told it shouldn't use any between 5000 km services. I just bought it with 200,000 km (120,000 miles) on the clock. It hardly produces any blue smoke and there are not any leaks. The car has plenty of power, runs quietly, doesn't seem to smell when running, and seems to have been looked after generally, though there is no service record. Compression is 158, 158, 132, 132. I'm told that the rings might be sticking, and using a detergent oil might fix the problem. I have just started using Shell Helix HX7 10w40 synthetic oil. I've read that this might help, but haven't used it for long and haven't had an engine flush. Do you think the engine flush will be a good idea, and should I continue to use the Shell Helix or the Castrol 5w30 mentioned in these forums? The dealer that sold the car has taken a couple of odometer readings and appears to have measured the oil used to top up. He suggested 3-400ml over, I think, about 300kms was reasonable for the age and mileage of the engine. Is this fair? I'll be taking the car back to the dealer next week for another reading of oil consumption and odometer, and want to have some idea what might be wrong when I have to try to negotiate. Could there be another wild factor such as catalytic converter or butterfly valve as mentioned in other posts here - excuse my ignorance - did not understand these references. Sorry for so many questions. Not expecting any simple answers - just maybe some suggestions for my meeting with the car dealer's service rep. How much oil should the car be using? Is this a common problem at this mileage? What should I do? - Regards, Phil (Tasmania, Australia)

Re: Just bought 2002 X Trail - using oil


Hi Phil,
My Xtrail started using oil after it had around 120k on it without a smoky exhaust and after reading a post by another member about the timing chain tensioner needing oil pressure to function correctly at higher rpm and the standard 5W30 grade oil not giving enough pressure at those rpm and it not really being suited to our higher summer temps, I changed to 5W40 Penrite full-synth.
The oil usage stopped and so did the suspected noise from the timing chain tensioner.

So keep with the 10W40 and stay away from the 5W30 now that your engine is in the older age bracket and let us know how it goes after a few thou k.

Re:


Hi Kev,
Thanks for the tip re the oil - I will stay with the synthetic Shell Helix 10w40. I don't think I've put enough in yet to tell how it is affecting things. Have to stay with the arrangement with the dealer and take the car in this week to read the odometer and oil level to estimate usage. I've got to keep him onside in case the rings need replacing, though I guess I'll be lucky if he contributes to the cost if new ones are needed. Another mechanic said that would cost $3500 because so much stuff would have to be taken off the motor. It might actually help to take the motor out. I sure hope this isn't necessary and the cylinders don't need to be re-bored.
As the car isn't smoking, the engine runs quietly and smoothly and there seems to be plenty of power and I've been told the compression readings aren't bad - just maybe flushing the oil and refilling with the synthetic 10w40 will stop the oil use.
Anyway, it will be interesting to see how much has been used and the response from the dealer on Tuesday.

Re:


What do people think of the compression readings 158, 158, 132, 132 ?
What would be the maximum acceptable oil use over, say, 500kms?

Are those compression pressures in PSI ?
Your model Xtrail should have 181.3 PSI standard with a minimum of 153.7 PSI when tested at 250 RPM with a maximum differential between cylinders of 14 PSI.

Re: Just bought 2002 X Trail - using oil


Thanks for your info Kev. I will ask whether the compression readings 158, 158, 132, 132 are in psi. I take the car to the dealer tomorrow for oil usage measurement (with odomoter reading). If those measurements are in psi the dealer's service rep is wrong that perfect compression is 160 and the lower readings are too low and the differential is too great. If so, do you think this explains oil usage and could it be rectified with flushing and continuing use of synthetic 10w40? I guess the flushing has to be tried. If no help, I wonder whether the dealer has any responsibility to replace the rings with some cost to him - given that I paid $8000 just a couple of weeks before discovering the oil usage. Thanks for your interest Kev - must admit I'm a bit lost - Phil

I would not do anything myself as it could have the dealer argue you have made the condition worse and instead push them for rectification since using that much oil is not a normal condition of the engine and the fault should be rectified under their warranty provisions.
Ultimately they should be pulling the engine down to replace the rings and especially check for signs of loose butterfly screw damage to the pistons.

If they argue about the compression figures then let us know.

Re:


Well Kev - good news! After dipping the oil and reading the odometer again today, the service manager verified that the car was using at least a litre of oil in 500kms and sent me back to the manager of the dealership. Straight away, the sales manager said the engine was 'stuffed', and offered to replace it at no cost to us with an engine reconditioned by them with 12 months warranty! He said to bring our car in at our earliest convenience and borrow another X Trail while the engine is replaced. He was talking to my partner and me at the car (full of mobility equipment for her) and said 'We can't see you stranded, can we'.
So this looks like the sort of car dealer you need. Will post brief updates, thanks for your concern - Phil

Re: Just bought 2002 X Trail - using oil


Hi Kev and others,
The car dealer has been marvelous, if only others were this good! The sales manager said he was having trouble finding a suitable engine, and offered us a 4 years newer car! It is a beautifully maintained 2006 ST-S 40th Anniversary model - similar mileage, unmarked paintwork, interior, smooth engine, gearbox, clutch, steering, suspension - an apparently sound vehicle with service record up to 150,000 kms. He even transferred the new tyres and unmarked wheel trims from the other Exy. The oil is remaining clear and the level is not going down. Needless to say we are very grateful and enjoying our car. So, thanks for your interest, glad to bring good news! - Phil
