The Amsoil has a good track record look at the use of the car . Look at the miles on the car.Look at the age of the car. The car sits alot. Solaris Ship that car out to me and I will keep it excercised for you !!!

Results of Delo 400 15w-40 in race engine

Finally got to tear into a motor I've raced on the dirt track. I've run Delo 400 15W-40 almost exclusively.
Motor is a 402 BBC. Steel crank, 7/16 rods, Federal Mogul tri-metal type bearings, KB hypereutectic pistons with around 8.5:1 compression, Crane flat tappet hydraulic cam, oval port heads with small valves, hard seats for exhaust, stock type ball pivot rockers, standard volume oil pump modified for higher pressure, homemade oil pan (based on factory truck pan) with trap doors and windage screen and right side extension, cast iron exhaust manifolds, high rise cast iron intake manifold, Q-jet and HEI. Rod and main bearing clearance 2.5. Self imposed RPM limit of 6200, with occasional forays to 6500. I did not have this engine balanced; after weighing parts and crunching numbers, I determined that with the bigger rods but lighter pistons I was at 51% to 52% overbalance. Fuel was 93 octane pump gas with no additives. We were allowed to run race fuel sold at the track but I figured I didn't need it given the CR.
This engine was in a stock type class that allows a few modifications. The big block was legal for the type of car.
I put almost two seasons on it. Missed a few races for work, crash damage, etc. During that time there were no failures of engine internal components. I did have one rocker nut that backed off and caused a dead cylinder but that was a lock nut issue.
I had more power than I could put on the ground. Modulation of the throttle was necessary to control wheel spin. Basically, it ran fabulous and I had more power than the rest of the guys, who were running small blocks. However, being 400 pounds over class weight and all of that being on the nose is detrimental to cornering performance! Lots of fun though.......
Oil fill was 7 quarts of Delo400 15w40, both old and new formula, along with about half of bottle of STP blue, which seemed like a good idea, but in retrospect probably was not necessary. Filter was a Delco PF-935. The oil filter bypass was left intact and functional, albeit with a heavier spring. I changed the oil around 15 race nights or so, each of which include a heat and a feature and packing the track.
Examination of the bearings revealed a polished look to the first layer of bearing material. There was no wear through the first layer. The part of the bearing near the cap parting line, where the bearing thins slightly, was untouched. There was no pitting, spalling or galling, just some minor light scratches in a few places.
I was surprised by the condition of the bearings. During a feature in May of last year, the oil filter got knocked off the filter pad due to running over a ridge at the very bottom of turn four that was left from track grading. (The oil filter sticks out about an inch and a half below the oil pan, not a great situation but neither here nor there) I ended up cross ways in turn four after spinning out or tangling with another car or both, I forget. I quickly backed down into the infield to get out of the way of oncoming traffic. Didn't look when I took off again moments later. I made it about 3/4 of a lap at race throttle before I noticed the oil guage reading about zero! (This is where a low oil pressure idiot light becomes useful) I immediately shut down the engine and coasted out of the way. The following week I debated pulling the oil pan and doing some inspecting, then decided to put on another filter, refill and see what happens. It sounded ok on start up and had same oil pressure as before. I decided to keep on keeping on and it made it with flying colors.
Conclusion: Delo is good stuff!
That is almost exactly like the last engine I had in my boat and I ran Delo 400 15w-40 .I also had great results . I have also ran 454+ci engines running 7,500 to 8,000 rpm with Delo getting equal results. I think there really is asomewhat in general misunderstanding of engines and oils here.

Besides There was A Season Sweep for Teague and Amsoil!!!
I had to come back and add Syn is recommended for this engine so I would stay with a syn.

By that I mean all other things being comparable (visc/service length/severity/etc.).

5. Cleaning up deposits left by mortal oils
Did I miss any Pablo?
I know bait when I see it.
I could ignore it, but then people would say I ran away or some other bunk.
1) Applies here. So?
2) Not sure people say "background noise" when they see a high wear metal UOA. Pretty unusual to see those here, except when something unrelated to the oil choice happens.
3) Yep, see 2 above.
4) See 1 above. (You are repeating already)
5) Clean-up happens with Redline all the time. So?
What's your exact point? Post up those "Amsoil and have high wear numbers" threads when you get a chance.

My point is that sometimes even a decent oil can do a bad job of protecting a particular engine or engine type. The oil this poster used met manufacturer specs yet the UOA wasnt what I would call a good one. Yes he drove his car hard, I drive mine hard, as do many sports car owners, thats what they are designed, built, and marketed for. I understand the need for politicians to tap dance and shift blame, but I dont believe it's necessary on this site even by paying sponsors. I also think they do themelves a disservice in the long run by cheapening a good name they might have worked hard to establish. I didnt mean this as bait, but it was somewhat tonge in cheek.
Disclaimer: I currently have over $300 worth of Amsoil for my Rotax and will buy more when I run out next year.

That's exactly why I don't tap dance. I try to call them as I see them, I recommended a race oil in this application - even for 1 track day. Two track days is way harder on an oil than driving hard on any legal street. I never tap dance and and I never tell people they should use long drain SM oils for racing. Any brand.
I also try not to infer too much from a single UOA - and admittedly it's a stretch to say no other API SM 5W-30 would have done any better or any worse in this case.

only the iron is high. Look at the use of the engine The car isn't driven much.I would say there is no problem at all and Amsoil did its job without any problems.
