Long term reliability of the 2WW engine.

[RossTA]

Good morning, 

I am wondering how reliable my 2017 2.0 D4D Rav-4 will be long term. The engine is the BMW sourced 2.0 diesel (2WW engine).  
 

I'm asking because I am possibly going to be moving work stations and it means my mileage will increase by 2.5 times. So my annual commenting mileage would be nearly 27,000 miles a year, before any personal mileage. Whilst I am looking at moving closer it is for the time being if I do move work stations. The main concern is that post 100,000 miles a lot of people seem to have oil burning issues with this engine. I have my oil changed every 6,000 miles or 6 months which ever comes first. I am currently nearing 56,000 miles and the majority of my current commute is mostly fast 70mph A roads and a tiny part of urban driving and the potential work commute is fast A roads and then motorway with a tiny amount of urban driving. 
 

Can anyone advise if this particular engine is unreliable post 100,000 miles or if the maintenance I am doing now is going to keep it running fine. I do have it serviced at a garage which uses the Castrol Long Life (LL) oil as it is a BMW engine and quality oil filter. I check with the garage to make sure they are using the correct specification oil which is 5W-30 C3.  I am more than happy to ask the garage to use the Toyota 2WW PFE C3 oil if this makes a massive difference to its reliability even if it costs that little bit more. 

The car doesn’t have ad blue and is run on Shell or BP fuel with the occasional dose of V-Power to keep things clean on the inside.  
 

Can anyone give me any advice/tips etc not just for the engine but the car as a whole. 

Many thanks,

Ross.

Generally speaking stick to what you are already doing although I would use Vpower or similar in a permanent basis. Preventative maintenance and regular use is the key to reliability. If it is an EU6 compliant engine, Given the depreciation curve and you seem to be otherwise happy with it, I would keep it until it is beyond economic repair or you simply fancy a change. 150k+ miles should be a doddle for that engine. Might be worth looking in on a Beemer forum too? If you change I would still consider a diesel for your high mileage although the RAV4.5 hybrids (plug-in and non plug-in) can give diesel rivalling economy. I went from 35 years of diesels to a RAV PHEV and the economy is incredible.

I've never owned a 2WW so can't give any useful advice based on experience ...

Although Google informs me of reports of high oil consumption with the BMW based engine I've never seen any specific issues raised on this forum. Indeed, the only post on the 2WW that I can find was yours from last year! 😉

You really must service the car in accordance with the schedule and use the correct specification of fuel and oil - as per your previous thread. That said, I can't see Toyota commissioning a unique oil for that engine so as long as the oil being used fully conforms to the required spec you should be fine.

Modern diesels, or more specifically their emission control systems, don't take kindly to short trips - but that is not what you are proposing. Long motorway journeys, driven sympathetically, provide the ideal environment for the modern diesel engine. So as long as you treat it well, that should give the best possible chance for a very long life ...

As Adrian says above, best value is to keep the car that you already have and change it as soon as it feels that it is becoming, or likely to become, unreliable.

Modern hybrids are brilliant and beat the equivalent diesel for economy but only you know what you true requirements are. 🙂

@Flatcoat Thank you for this. I’m happy to keep my Rav 4 for the time being I was concerned if post 100,000 miles it’ll be a money put as I’ve always kept my cars till they have near enough fallen to bits so given my potential uptick in mileage I’d be over 100,000 miles in a year and a half. So I will keep doing that and if my wallet allows I’ll use V-power or equivalent from now on. 
 

Cheers.

Hi Phillip42h,

Thank you for this. I know I posted last year about the required oil as the manual was confusing and that my previous car had a specific code so that many different brands of oil could be used with no issues.
 

I do make sure it is 5W-30 C3 oil so I take it that as long as it is that grade/specification and of good quality I should be fine? The last garage used Castrol 5W-30 C3 LL oil which is used in the BMW engines. 
 

My car is very looked after and so hopefully by doing very regular oil changes and servicing (Even if a bit overkill) should mean my car lasts a good amount of time. I’ll be honest I reckon my next car would be a self charging hybrid but hopefully that would be many years down the line. 

Thank you for your help.
