What oil do you use and why?

[Bunky]

The general consensus at BITOG is that there is no "bad" API SM oil for regular use (no super high/low operation, racing, etc). The specs require a good oil. It is just about personal brand preference. Every brand has loyal and satisfied users.

Where do you find that? This may be good for my IT car but I have never come across M1 labelled as racing oil.

I've heard a lot of good things about it but so far I've only used it for Auto-RX treatments. I have a sample from the rinse phase of my VW but haven't sent it to Blackstone yet. I'm not sure there's a point, with all the dirt that should have rinsed out.

I, too, have had great luck with M1 in the past. Both my current (road going) engines are all varnished up now on M1 0W40. At a minimum I'm reducing OCIs but probably changing oil, just haven't decided yet. Possibly German Castrol in the winter and M1 TDT in the summer. At 105K your Mustang is a low mileage car.

Mobil has a bad habit of discontinuing great products like Mobil 1R and their Synthetic Spray lube. It has been discontinued for quite some time but I was getting it from AV Lubricants-Your ExxonMobil Oil Distributor! but they have run out of stock and I cannot find it anywhere else

I currently have RLI Biosyn(vegetable oil) in my SRT8. All my driving is in town and it shows great resistance to fuel dilution in analysys on BITOG and other forums.

I use BMW full synthetic 5w30. I have used this for 8 years in all my cars. Why? I get it CHEAP lol and it workds great. It is just rebottled Castrol of Germany oil. If I had to pay full price for oil I would probably still use this or try Royal Purple

Setec do you experience any oil burnoff with it in the rsx? All I do see is posts on crsx with people getting terrible oil burnoff with M1 on their rsx.

I've been using Mobil Clean 5000, and it seems fine to me. Autozone usually has good deals on it 5 quarts + oil filter for about $10-12. I really don't think my driving habits and mileage warrants a synthetic oil. As long as I change it out every 6 months I think I'm OK.

Johnny, last crankcase full was mostly 0W-20 SL that I had bought up when they discontinued it, with a quart of 5W-20 SM. I was 2/3 of a qt. down when I changed it at 5K.

In the old days my GM's used to burn about a half quart of 5W-30 every 3000 miles.

EDIT: Interestingly enough, I've just recently gotten so anal I started writing down the oil level at the time I change it (if I remember) on all the cars I do, just so I can monitor any changes in consumption and/or predict when oil will need to be added. Must be the extra time I have from not going to nightclubs anymore.

I used to run Castrol GTX for a long time, but now I only use Mobil1, even though it's been getting a bad rap lately. I have been thinking about going to Syntec or Penzoil Platinum.

I was running Mobil 1 until I found out they had switched to group III. I still think it's the best oil for the price and you should use nothing less. However, I've switched to Royal Purple to see how that works out, I'll be find out on the next oil change. I put 10w40 in my Stealth and 10w30 in the GTC. The transmission in the Stealth is going to get SyncroMax while I'm just going to use straight 10w30 in the GTCs transmission. The t-case and the rear gearbox are getting MaxGear. As for filter, anything but Fram, but I tend to stick with Mobil 1 or K&N filters.

As per dealer recommendations, Mobil 1 5w30 Super Syn every 5k miles.

This, however, is full syn:
