I suppose it depends how long you intend to keep your car but there was criticism of long life oil change intervals in a recent evo mag.they did an article on whether turbos last well or not with head of UK turbo technics. He said that regular oil changes are essential. Dirty oil contains carbon contaminants that scratch turbo bearings leading to failure. Current long service intervals are to blame. If you change oil regularly follow a sensible warm up and cool down regime and change the air filter too then there's no reason why turbos shouldn't last really well. The dirty air filter causes the turbo to work harder to move the air hence causing overheating or faster wear.

So there you go. I've always felt minis UK regime of two years or around 18-20k miles was far too long and change mine every year at around 8000 miles. Seems according to the head of turbo technics my thoughts are right. Whether or not we keep our cars an oil change is very cheapcompared to a new turbo so I will continue my yearly change. Someone else may get the benefit but this one might be keeper!0:)

I have my oil changed every 8 to 9K if it needs it or not. Sure you can say I waste my $$ but an oil change is cheaper than engine work after the warranty. Just to compare it on my Semi I run the oil 100K before the shop changes it but we have a bypass system to keep the oil clean.

Good advice. My oil gets changed about every 6 months or 6,000 miles or so. Works out to every April and October, right before the summer heat kicks into high and right after. You should see what weeks and weeks of 110F and higher temperatures does to oil.

and the brain lets not forget the brain. You can see it everyday with them stupid drivers on the road here in Phoenix and Las Vegas.:D:D

Btw I had my 1st oil change at 1K after I broke the Engine in Dealer said I do not need it but them old wife,s tale habits are hard to change. I did it with all my new cars.

When I got my new engine I changed oil at 1.2K miles. I change it now at 5-6K miles. I'll still use the "free" dealer oils changes for as long as that lasts and will cover the others myself. I've been doing it this way for 50+ years and don't see myself changing now.

Through an auto shop program in high school I got a job doing oil changes and eventually other stuff at a dealership. Oils have gotten better, engines more efficient but still can't let go everything I learned. It's cheap insurance and gets me my alone time tinkering in the garage. Plus, as they say, an ounce of prevention is worth a pound of cure..

And...if we change oil every 10000km (that is april and october...the same months in which tyres are exchanged...) could be a good idea use oil more specific?
I mean 0w-30 for winter and 5w-40 for summer?
And ll4 is always mandatory even if the oil is pratically always fresh?
In any case two weeks ago I put 4.75 l of mobil1 formula 5w-30 in my B48 9000km old.

Ironically the turbo would prefer the 0w-30 for cooling with higher oil flow. 5w-40 might be better protecting hot engine bearings during low rpm with full power. If you keep the revs up above 2000 - 2500 then the thinner oil is better, again because of flow cooling.

I've done oil analysis for my engines and the biggest problem with longer oil drains for me has been loss of detergency. I can see this leading to excess carbon and maybe deterioration of engine and turbo seals.

I am of the same opinion.
These excessively long service intervals are not good for the engine.
I got my independent MINI specialist to change the oil & filter at 14,000 kms recently. I'll get it changed again in another 10,000 kms and then get MINI to do it as part of the TLC package in another 10,000 kms.

My mini dealer won't, so I take to my friendly BMW repair shop for interval changes. The dealer will only change it within 1,000 miles of 10,000 mile intervals. I will check with the only other dealer within a reasonable distance for the next purchase. I have bought 2 JCWs from this dealer and the first one they changed whenever I requested it without charge. But, they have changed a lot of personnel in the time since the first purchase and obviously not for the better in my opinion. I initially had a hard time not changing the oil in 2,000 mile intervals from old school days, but I changed my own oil then and bought it in bulk.

My 2015 JCW is still under 700 miles so I will likely change oil & filter soon myself or wait until cooler weather & about 1,000 miles. I think it's fine either way. My dealer knows I prefer doing it myself. The 100 mile round trip to the dealer plus my time just isn't worth the free oil change. I enjoy it anyway.... great therapy & I have a lift so it's s no brainer for me! ;-)

I used to drive a Honda Element. The recommended oil change service was every 10,000 miles, changing the oil filter every other time. I did this for the seven years I owned it and it ran like new until I traded it in. Never once had an issue with it the whole time I owned it. Just got my first scheduled oil change on the Mini with 2,800 miles on it.

Ok...next will be 0w-30 all year long!

So is the recommended MINI synthetic (Shell) 5W-30 all that different? I wouldn't think it makes that much difference. Weather conditions & the way you drive the car are probably the most important variables.

While it's under warranty I go with what MINI recommends and use the MINI oil. They changed from Castrol to Shell as the preferred oil but who knows what the actual difference is. Shell probably gave them a better deal. Based on conditions MINI recommends a range of 0W-30, 0W-40, 5W-30 and 5W-40. Choose from those and you'll be fine.

Interestingly enough the Mobil 1 website states that they do not make an oil that meets the BMW/MINI specifications. Mobil 1 Link.
