  1. Codes are not diagnoses, they are indicators of a fault condition and typically have several possible causes. See: http://p1670.enginetroublecode.com/toyota-rav4
  2. Does "D-cat" mean insurance category D or that you've removed the catalytic converter?
  3. Easy enough to check for parasitic draw yourself with a multimeter. http://www.agcoauto.com/content/news/p2_articleid/211
  4. See here: https://jalopnik.com/this-is-why-the-gas-pump-keeps-shutting-off-on-you-all-1842036809 Be careful to avoid over-filling as this can damage the charcoal canister which is quite expensive.

    I don't want to keep repeating the other things I've already said as I'm sure this thread is getting boring now, but just consider this - if the manufacturer's maintenance schedule is trustworthy then why do they claim that their transmissions are "sealed for life" and don't need fluid changes? Pretty much everyone agrees that if you plan to keep the car a long time this should be done. I think that alone proves my point.

    Appreciated, and that's the great thing about forums - everyone can share their opinion 🙂

    This may be true, but it's based on a designed service life. They only really care about the car making it out of the warranty period, beyond that their obvious strong preference is to sell you another car.

    The service intervals given by the manufacturer are (by their own admission I think) usually specified for cars operating in ideal conditions. 1700 miles in six months is not ideal operating conditions for any car. For the sake of the cost of an oil change why take the risk?

    I would because of the reasons already stated. My wife has a rav4 and does very low mileage so I change the oil every six months because this is considered extreme service. There's plenty of information on the internet to back this up if you care to look, here's a couple of quick links: https://www.dummies.com/home-garden/car-repair/how-often-you-should-change-your-oil/ "You’ll be surprised by what some “extreme operating conditions” are: If you do a lot of stop-and-go driving in city or rush-hour traffic, make a lot of short trips each day and leave the car parked long enough to hav

    Most of us can do simple maths though. 1700 miles / 180 days = 9.44 miles/day, so either lots of short journeys or some longer journeys and the car was sat for long periods due to lockdown which the OP does appear to have hinted at. The end result is the same in terms of moisture building up in the oil. An amusing comment given that you're repeatedly ignoring presented evidence haha.

    Louis is a good guy, and honest. That wasn't just some link I found randomly, I've known him for a long time and we talk every now and then and he's taken the time to help me with many car problems over the years even though we live in different countries and he has no prospect of ever making any money from it. He has a weekly call-in radio show where he helps people with their car problems and takes a great pride in being honest and treating his customers fairly. If you'd read much of his website you'd eventually realise that his entire business and ethos is centered around saving people mone

    Runs a garage that also fully rebuilds engines. Which do you imagine is more profitable for them? You'll never save enough on oil changes to pay for one engine rebuild.

    Nonsense. See the link I posted above. Also if you stop to think about it for more than a minute or two you'll realise why blindly following the manufacturer's recommend intervals is silly if you intend on keeping the car a long time. At the point of sale, low maintenance is a selling point, especially for fleet buyers. The car looks better on paper because its running costs are apparently lower. But the company selling you the car only really care about it making it out of the warranty period, beyond that.. who cares? If it suffers catastrophic engine failure at 110k they can sell you a

    You might not, but the manufacturers of vehicles do. See here for further reading from someone who actually knows what they're talking about (very successful garage owner, working on toyota/lexus for decades): http://www.agcoauto.com/content/news/p2_articleid/212

    Also if you read your owners manual carefully you’ll find they usually recommend a shorter interval for cars subjected to extreme service. Not being driven very often falls into this category.
