Changed my oil last night due to a header swap, last oil change was approx
1200miles ago w/mobil 1, usually I run royal purple but my shop was out,
long story short, the mobil oil was still fairly clean but very thin and almost like water, friggin wiped off my hand with a paper towel w/no residue
also noticed my drain plug magnet was full of sludge which has never happened before. just curious if anyone else has had any issues lately?

by the way, 2001 WS6 only 49,000 oil changed every 3000mi

what weight oil? also, if you never had "sludge" before and you do now..that's probably a good thing, as the mobil 1 is actually helping clean the engine. just a thought..

i dont know what weight you were using but when i use mobile i use the 0W40 german blend its much better oil than the regular mobile oil

Stick with the RP.

Mobil 1 5w30 is actually a little thinner compared to almost all other 30 weights. I would use something a little heavier, or stay with RP. However, like already said that sludge is just the detergents in the oil cleaning your engine! Good thing!

i've ran mobil 1 0-30/40 for years with no problems. it's funny to see people split hair over oil, when it reality...as long as you change it regularly, odds are you will throw a rod LONG before the use of "poor" oil has a chance to take its toll on the bearings, etc.

i hear of sooooo many people running RP then they break open their engine and find sludge EVERYWHERE... the Mobil one probably cleaned it out down to the drain plug...

I'm almost positive the Mobil 1 cleaned your engine. have you ever taken apart an engine that ran only Mobil 1. The inside of the engine looks very CLEAN.

Well I can say that what you "heard" is bull. RP leaves virtually NOTHING on my oil plug and I've been using it for 7 years now on my Camaro and 4 years on my Vipers before that. I have done oil analysis on many occasions with excellent results.

Also if the "sludge" was on the magnetic plug, it wasn't "sludge" but rather fine metal particals. Why else do you think it was on the magnet? That's because you had more engine wear using the Mobil 1 than with the RP.

Ive ran RP and M1 they were both ok, but now i run synthetic Rotella T and i'll never switch to anything else.

The only reason this sludge is on the drain plus is because its a low point in the oil pan. If you're finding sludge at the drain plug I would feel better than not finding any at all.

StevieZ

Sorry but that's not true. If it is sticking to the magnet, then it's metal. Sludge will drain with the oil. Sticking to a MAGNET should tell you something. Give me a clean plug anytime.

I've run mobil 1 and castrol syntec blend for years in my daily drivers with good results but have recently swithed to NAPA synthetic in 2 of them to see how that goes. Used royal purple in my T/A but spun a rod bearing 1000mi later so I never had a chance to see how it reacted compared to the Mobil and its too expensive to play with that oil in other cars to see results.

i concur with this statement.

I used to run Mobil 1. I had excessive noise valve train and piston slap, etc..

Car was cammed with about 40K miles. I switched to redline 10-30 and My noise was cut in half! I have continued running it for 25k miles, and recently pulled the pan for rod bolts. The engine was amazingly clean, and I was very surprised, as I beat the **** out of this poor car at the strip. Am I saying go buy redline, its the best, no. But I seem to have alot less metal particles on the magnet (almost non existant, used to be a little with M1). All im saying is in my application, It was amazing how quiet my engine got, and how little it seems to wear vs M1.

Hmm... M1 has never given me or my old man problems. He ran it in his 95 Camaro (V6 but w/e), not even the valve covers were taken off until 298,000 Miles, he owned it since new and used only M1. Lifter failure at 298k, sold it due to tranny failure shortly after. When the engine was in pieces, MINIMAL sludge, all parts looked BRAND NEW.

His 02 Monte SS, same deal but saw a lifter failure much sooner (220k miles), ruined the cam as well, everything looked new, minimal sludge, normal). Fixed it and it's running great at 235k+ right now.

My 00 T/A - M1 since new, reciepts to prove it. Car runs great, never missed a beat, never had the heads off the car. Currently at 113k. It's funny that you say it came out so thin. And I HIGHLY doubt all that sludge occurred over 1k miles. If it did, you've probably got much bigger problems.

Like some have said, I'm not saying MY oil is the best, it's worked and worked well so why fix something that aint broke?
