What oil do you use and why?

[baker]

Castrol synthetic, done by the dealer because its free of charge.

Fact is if you are doing 3K-5K oil changes ALL of this discussion isn`t worth @#$@# because any cheap conventional oil WalMart happens to have on sale will go to 5K easily.

I`m not convinced this is true. I`d been using Mobil 1 products for years, with excellent results. My old Pathfinder had 215K on it when I traded it, and was clean as a whistle inside. Compression, power and economy were the same as the day I got it (at 68K). Both my current cars have over 174K on them, and I`ve used M1 exclusively with 10K oil change intervals until recently. Both engines are varnished up inside. I broke a timing chain at 164K in my VW. That`s what got me looking at BITOG. I did an Auto-RX treatment using Rotella T 5W40, but now I`m experimenting with different oils and sending samples to Blackstone. The more I read BITOG the more confused I get; it`s information overload I`m afraid.



I think the engines in my garage today are harder on oil than what I`d owned in the past. Some of the new direct injection engines are much tougher still. My VW sees 6000 rpm every day. It will take a lot of oil analysis before I`m comfortable exceeding 5K OCI with a synthetic.

Redline oil all the way!

from everything I`ve read and heard redline is t*t`s all-around.

do you like the rotella? thats what I`ll be switching to.

^^Love Rotella T 5W40, that and Penzoil Platinum are my go too`s for my two cars.

the consensus on the jeep forums is it pretty much the best for the 4.0 so I have high hopes. I was just looking around on the shell forums and it seems they have a new version out but the only thing changed is it no longer carries an sj rating and not for use with 07` up diesel`s because it has more zinc and phosphorous than the new certification allows. which is still great for the jeep:xyxthumbs

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.

couldn`t agree more.

I also run Mobil 1 Racing oil

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 have been running Mobil 1 in my vehicles for 20 years with great results backed up by many years of used oil analysis. The Mustang has never seen anything but Mobil 1 and she is still purring like a kitten at 105K...

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

[manicrodder]

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.

[imported_sal329]

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

[JaCkaL829]

I use Mobil 1 because I like to pay full synthetic price for an oil that`s not really really a full synthetic anymore.

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.

[Setec Astronomy]

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.

[mhadden]

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.
