hey guys, i'm sure this has been covered before, but i'm new to the forums and i thought it might be good to get some new opinions.

i have an 04 mc, it has about 90,000 on the clock. runs like a top.

i've run amsoil 5-40 euro formula since she was new.

what oil is in YOUR crankcase?

 

olive oil

 

Royal Purple

 

Moble 1 full synthetic, 5w-30

 

In both of my Minis, a 2003 MCS and its replacement, I have used and continue to use the Mini branded Castrol.

Right or wrong that's what I use.

Hope this helps...

 

German Castrol, a damn heavy 0W-30...essentially a very light 5W-40.

Mobil 1 Extended performance. it's good for 15,000 miles, since the MINI only wants you to change the oil every 10,000 miles or so I wanted to make shure the oil would hold up. I do change the oil filter every six months.

 

Amsoil European Formula

 

Amsoil European 10W-40

 

I use the Mini recommended Castrol since it's under warranty still.

 

Mobil synthetic 5-30 here...I get it in the big jug at Sam's Club

 

Castrol SynTec 5W30

 

right now, Mobile 1 full synthetic extended performance 5w30, but thinking about switching to Royal Purple 5w30 or 40

 

Mobil 1 full synthetic since new changed every 5k mi

 

This is just the topic I need help with! I went to get some Castrol SYNTEC oil (5W-30) and noted that the OM states you need an API of SH or higher. The oil container says it has API SM/CF... Is it okay that I run the SM grade or is it of lesser quality than SH?

Thanks!

AMSoil 0w-30 signature series.

castrol full synthetic 5W30. ( changed every 5000 ) and i dont care what anyone else says about this. call it a "sleep better at night" thing

 

Same here. 5K changes are easy to remember and gives me a chance to check plug torque regularly. Artoo also runs like a top and has now passed 75,000 miles.

i personally go 8000 miles between changes, i've had a UOA (used oil analysis) done, and the amsoil has plenty of life in it at that point...

 

Mobil 1 and changed every 6 months. Easier to remember a date than it is mileage..........

 

Anyone going to help on my question please? Or should I start a new thread?

 

aorr , everytime API standards change , the second letter goes up one letter. SM meets a higher standard than SH . So yes , SM will be fine .

 

Redline

 

SM is a better grade.
