    Mixing Oil viscosities?

    The only thing I now know for certain is this whole oil business is confusing! There are so many factors to consider, cost being just 1 of them. I am a firm believer in "you get what you pay for", so that along with Enzooooo's replies now has me edging (apologies) towards buying a few litres more of 0w-30, and leaving the 5w Magnatec for the missus' Clio. At least that way I will know exactly what's in there and not be wondering what chemical interactions might be going on or not. Since I've had the car I've only ever used 0w Edge and the oil levels are always consistently good. She burns very little oil, as I rarely if ever have to top it up. I would like to keep her like that. I do a lot of small journeys from cold, so again 0w might be kindest to my engine. Anyhow during my "research", I came across this vid. Worth a gander I think. https://www.youtube.com/watch?v=ASAdkJydBFU

    Mixing Oil viscosities?

    One point I want to dispute with Enzo. He said and I am mixing "any old stuff". Clearly that is not what I'm proposing. These oils appear to be very similar, albeit the Edge will have better performance on start-up at extremely low temps. One thing I cant figure though, is why the huge price difference? Is it just marketing, or is there a real and substantive difference between the 2? Why is Magnatec always so much cheaper? I actually might mix a small bottle of the 2 oils 50:50 and put it in my freezer (along with a sample of the 2 unmixed oils) overnight and see how their viscosity is affected, if at all

    Indeed. Well I've ordered it from Halfords. The website states (as does the bottle image) it's BMW LL04. If it's not on the bottle when I go to collect, then I wont be having it

    Please educate me.

    Fair point. Like most things in life, if it keeps you awake, then probably best to avoid. PS the 0w-30 is in the post!

    Cheers Guy! I think if we start a Brexit and an oil combo thread, then we'll have great fun. On a serious note, I can agree with both of you. On one hand Mike makes sense as the oils are practically identical. Both BMW LL 04 & both FULLY synthetic. I will not be track driving, just very moderate everyday use. Also I will not be driving in extreme weather conditions, eg Alaska or Siberia. Therefore it shouldn't make any difference to me. I will end up with something like a 2.5w-30 grade oil. Then we have Enzo who introduces (quite rightly) a large dollop of doubt. ie we do NOT know with 100% certainty how the chemicals/additives in these 2 oils will interact. They may not interact at all. The interaction might be totally benign. But it might be very negative, and damage my engine! I will be saving/losing approx 25 quids worth of 0w Edge, to take that risk. I'm still

    Wow! I never thought oil could be so involved, interesting or contentious.

    Mixing Oil viscosities?

    Apologies in advance if this topic has already been covered. My F10 is due an oil change. Last one I did, I used Castrol Edge 0w-30. Having bought too much I still have approx. 2.5 litres left over. My dilema is this. I've managed to source Castrol Magnatec 5w-30 at almost one quarter the price of the forementioned Castrol Edge! Both oils are BMW LL 04. Both are Fully Synthetic. Both Castrol. Would you recomend mixing roughly 50:50 ? Will my engine explode? No seriously will it make any difference? Thanks in advance!
  9. i see from one or 2 videos online that some people recommend tapping the calipers with a rubber mallet in order to free any air bubbles. what would you guys say, is it a useful thing to do?
  10. Thanks again! I'm happy to give it a go. Time to roll my sleeves up & get stuck in. Well in the morning at least.
  11. Thanks Andrew, that's probably the way I'll proceed. I like to do these things slowly. I think 15psi should be adequate. My plan was to use a turkey baster to syphon off most of the old fluid in the reservoir, top it off with new fluid, and then use my Pressure bleeder to bleed each wheel in turn, starting at the passenger rear, then drivers rear, then passenger front, and finally driver's front. To give it a proper bleed, how much fluid do you think I should be discharging? 500mL per wheel?
  12. Good write up. I am about to bleed my brakes and have bought a pressure bleeder as it seems pretty straightforward (I hope). I was wondering if there any need to pump after each wheel has been bled or should I just wait until all 4 have been bled? or does it make any difference?

    Heavy rain, Water leak

    Well I just put the insulation cover on yesterday. I drove for a week or so with it off, without any problems. Before putting it back on I smeared silicone sealant all around the yellow grommet. This was tricky and awkward as there aint much room to get your fingers in there, but hopefully I've done a decent enough job. TIP Block the drainage hole leading into the side/wing cavity with a piece of cloth, as you don't want to get sealant in there. Just remove the cloth when finished with sealant. I could not get all 4 T30s back on, only 3. The one behind those 3 pipes was impossible, so I've left it off. Will try again. My rear carpet has definitely dried out. TIP I would recommend using Baking Soda/Bicarbonate of Soda. I use to use this on my smelly running shoes and it dries them up and helps banish smells. All in all a PITA, but happy to have gotten to the bottom of my wet carpet problem. Routine maintenance job from now on.

    Heavy rain, Water leak

    I'm on the West coast so we certainly enjoy more than our fair share of Atlantic mist. Well after a weekend of very heavy nonstop rainfall, I'm delighted to report that my rear carpet seems to have dried out. Removing that insulation panel has helped for sure. I used a tiling drillbit to make a big hole in it. Probably replace it next week. I used some silicon grease around the rim of the yellow grommet, which will hopefully help keep water from entering. I had to utilize 2 beach towels to soak up the dampness in the rear footwell. There's a bit of a Dame Judy in the back but hopefully, that will clear in time. Once again my sincere thanks to all contributors for your invaluable knowledge & guidance!
  15. Mine is a 2013 with fairly low mileage (35,000). I'm semi-retired so time is not an issue. I am not in the slightest mechanical. In truth, I do all/most of the servicing myself which has saved me a small fortune. To date, I've done the oil changes (so easy it's embarrassing), oil filter (easy), air filter(easy), pollen filter(easy), cabin filter(easy), fuel filter(slightly more difficult). Also did the front brake discs and pads, which was the most challenging, but very satisfying.
