Id really like everybody to get involved here Its a Simple one this and goes a little like this just tell us what your preferred choice of Oil is? What do you use in your pride and joy? Hopefully that way we will get a database together of whats suitable for Oil Changes what the cans look like and places that stock it If you could do a little research and maybe go to the Oil manufacturers Website or stockists website and link the details here like piccys of the cans they come in etc it would be useful Not all Oils are available everywhere so by having this database it will give us all a reference that we can come back to when searching out Oil Also if you spot an Oil that maybe you don't use but is Suitable for our needs please feel free to post up the details here.

I think my hubby got it from our local car shop, they may have had some old stock left though. Mine are due for an oil change soon so will have to see if i can find some again

I use Castrol GTX 20W/50 too. It's commonly available here at any auto parts store or BP service station.
My two mates with Autos reckon Penrite HPR10 Gas 10W/50 is better, so I might try it next oil change.

Last time I spoke with a Castrol tech rep he recommended GTX 20/50 for older engine(Australia) I wanted him to recommend something a little lighter in winter but he refused to budge. Its usually the cheapest quality mineral oil in auto shops anyway.

According to their website Penrite used to recommend ATF in the transmission and HPR30 in the engine. ;D ;D ;D

Its usually the cheapest quality mineral oil in auto shops anyway. What was his name? I work for BP, who owns Castrol and I know some of the lubes and fuels tech guys. They don't normally recommend anything out of the ordinary, prefering the safe options. Whatever you do, don't use GTX2 or a synthetic or Penrite HPR10 that's not for GAS engines - the additives do not work with the wet clutches. Penrite HPR10 GAS is 10W50 so it will be a bit lighter in winter. But I feel a bit disloyal to my employers by suggesting it. I repeat, don't use HPR10 that's not for GAS engines, it has the nasty additives!

As previously Said i use Valvoline VR1 20w50 Mineral oil but i know a few of the Metro Auto Owners Prefer Morris 15w40 Mineral I noticed whilst it was cold Boris took longer to warm up and i am wondering now if 15w40 is favourable in colder months but possibly 20w50 in warmer months? As the weather has improved and Boris has recently had an Oil Change he will keep his Oil as hes up for sale. I may mention to the next Owner though that it may be worth trying 15w40 in the colder months ? Huggz Jodie

Good to see this topic being raised - as we all know how vital the oil is to our cars. I use 15/40 but have never been sure of the difference of merits between Mineral, Synthetic or Semi-Synthetic ?
Could anyone shed light on this?
I too have noticed that in recent weeks my Mini is probably due an oil change - as if I let it warm up before driving the gear changes are much smoother - but in these very cold conditions can slip.
Second point - how often do most owners tend to change their oil - I have been aiming for every 2000 miles and always notice a huge difference for the positive at each oil change.
Roger.

I'm going to try the Valvoline VR1 20/50 in Trogdor. The guy at Napa was so happy because his last customer who used to buy the stuff.. Um.. Died, so they've just been sitting on the shelf! I told him he may want to bring in another shipment since I plan to change my oil every 1,500 miles. Oil is the life of the car - I take it pretty seriously!

My life for the past 17 years has been oil (and for 5 years filtration). So I'll start out by suggesting you read this paper I put together for my Corvair enthusiasts a few years ago and still have thousands of downloads a month. It explains more of how to come up withthe right oil off the local shelf than a particular brand, since brands change formulations and certifications frequently. Also since many brands sell one thing in one country and the same name with different quality across the border. www.widman.biz/Corvair/English/Links/Oil.html Now let's get to our mini's. I'm a few months from getting mine on the road, but considering the automatic transmission uses the same oil, I plan on using the new motorcycle spec (MA2) oil in mine. Since is the latest in wet clutch protection, and I've seen it cut seconds off shift time in motorcycles, in theory it is the best for our engine/transmission combinations. This is my project car and details the monthly (?) progress www.widman.biz/Mini/English/index.html

Just rejoined the mini scene after 11 years away and now have a1988 Mayfair auto. I used to have a 1975 auto which had a horrible gear change. I put this one on semi synthetic and it transformed it. Need to do the oil on the Mayfair and wondering whether to go down this route again.

Hi All, I have used many types of 20/50 oils over the last few years and the done a bit of investigation into 10/40 motorcycle oil!!!! I own and run motorcycles which have wet clutches and run motul 10/40 which I am impressed with. So decided to take plunge and try it in my1275 auto!!! The car has done 2500 thousand miles on new oil and to say I'm impressed Is an understatement. The car shift gears smoothly and before had an intermittent flailing problem between 3 and 4 which has gone completely!!!! Im going to change oil at 3000 mile intervals so it is due to be changeD.

That is what I try to convince people. get the MA2 motorcycle oil and you will be happy. In motorcycles we see extended changes and not all the usual debris from clutches. They grab. At the wholesale level, the MA2 motorcycle oil is only about $1 more per gallon than a good car engine oil. The worst thing you can put in is a gasoline car engine oil with its slipperiness additives.

Hi again, yes motorcycle oil sounds attractive to use in an A.P. auto but its horribly expensive in Australia, the Scot in me thinks its a scam done by the oil companies, BTW, anyone else noticed engine oil turning red with use these days, mineral, semi synth, full synth? Jock

Just this weekend. I did 280 mile round trip. When I started, the oil was basically clear (Castrol 20/50 mineral). when I got back the oil was looking like someone added some auto trans fluid. It had that shade of red to it. While on the subject of fluids and long trips. At 10 miles out, my thermostat stuck and she boiled over. Took out the thermostat at roadside and looked for a station for more antifreeze. When U opened the cap, dish soap like foam gushed out. I immediately checked the dip. Phew, OK. Topped it up until all foam was dispersed. Car went 270 miles at half gauge on the temp scale.

That crack has all the earmarks of a misalignment upon assembly. You're right. Some bull-fist character was at her.

Re the subject of engine oil turning red I may have the answer to my own question, I suspect it the red dye in the 91 octane petrol sold at least here in Australia, I use it in both Otto and my modern car and both cars the engine oil develops a reddish hue, I use 98 octane in my motor bikes and it is almost clear and the oil in the bikes just darkens with age like oil used to do in the old days. Not unknown for petrol to be dyed in the past perhaps todays dyes are more persistant but benign? Jock

Motorcycle oil should not be much more expensive. Don't go for the oils for the big bikes without wet clutches. Look for the MA2 description, and pick your brand. That means it meets the right friction characteristics. This chart shows the difference in friction coeficient You can see that a MA2 oil will have about twice the grab as a normal car oil. The difference between Mineral and Synthetic will mainly be in how long you can run with it. Synthetic is especially better in real hot climates and city driving where temperatures go up. It will resist oxidation (darkening) better. Going back to price, shop around. I sell (retail) MA2 motorcycle oil for $3 more per case of 12 qts than I do an API SN motor oil for cars. That's 25 cents US more per bottle.
