    The 5w part means the viscosity of the oil when its cold . If you live in Iceland thats good.
    If you live in Mount Isa  the    20  means its  no good. 50 or more might be more appropriate
    The oil companies love to confuse things because it means they can charge more money.
    I  reckon the penrite full synthetic is the ducks fukin nuts.
    I have been puting it in the three holes for the past 4 years without an issue. 
    Only doneabout 20K though but all good

    Be careful with today’s cars  the the wrong weight oil can cause issues it’s not like the old days with oils
    Recently seen it with my own eyes we had a Mazda 3 at work which was at a change over year/month point 
    Well the tec put the oil weight  in that they where instructed to use  even checked out on cctv  
    Customer took the car hm all good parked it up next morning wouldn’t start  , they tried to jump it 
    No go this was a sat   Killed the battery in it  was towed in to work on Tuesday  would have sworn it had 
    Throw an a timing belt cranking with no comp at all  after few hours of digging around chasing the tail checking things out 
    Went back to the drawing board  and worked out the oil was wrong   After drain new filter new oil and cranking for 
    A few seconds than letting it sit for few minutes  than repeat   10 minutes later she’s all good and running,
    We have about 10 different types of 5/30  petrol/ diesel at work for different applications in our case we put it down to
    The lifters being pumped up and holding the valves open    Best way is is to what ever brand you choose check it 
    Out on the lube guide  for your application

    as far as im aware  i thought the oil is meant to stay in the lifters ? .. if it doesnt you get a terrible rattle during every restart. 
    but anyway its in the car now and it wasnt cheap either lol , if worst comes to worst ill just go back to sca and demand they give me the correct oil as it was their system that recomended that oil .. the 5w 20 is more specific to cold conditions as far as i can make out .. maybe 10w-40 is a bit to much as the way im reading it its more designed for bikes.

    Wello, most newer cars are running light oil like that for emissions. An SN rated 5W30 would be fine and 10W40 although not ideal probably won't do any harm. One thing to be mindful of is modern VVT systems etc aren't set up for thicker oils

    What car is it?

    A mate had CX7 which had a turbo charger and was told to change the oil very regularly.
    Apparently the drain pipe from the turbo could get blocked. The pipe wasnt big enough.
    Dont know about the CX9

    I did a bit of sniffing on line and it looks like it might be a V6 engine with VVT. Manufacturers will recommend different oil grades for different markets/countries and some guys from a Mazda forum in what looks like in the US were talking 5W30.

    Check your handbook and it should recommend a viscosity (don't be surprised if it's different to the oil cap) and a couple of other options if the preferred grade isn't available or for different temperatures.

    5W20 isn't really that common here in Australia yet but 5W30 SN grade oil is everywhere, either for your next oil change or if you decide you want to dump what you've put in there.

    Edit - I checked a few online oil selectors for curiosity after I posted this and Penrite recommended 5W30 - 10W40 (they're usually always higher), Castrol 5W30 and Nulon 5W20 - 5W30.

    Different climates use different weighted oils. Don’t follow what others do in another part of the world.

    My work ute is a ford ranger thankfully was on the piss with a mate the night before I dropped the oil
    I don't confess to know a lot about cars but I always pull the drain plug and have a beer until the oil has stoped dripping.
    If I had done this with my ute it would have cost me a bom For fuck sake.
