The gas station nearest to me has the same except it's 87 octane and $4.59/gal. I just use E10.

My data is from a summer race at Daytona. Qualifying is 230-250°F. Race day it's 280-300°F with oil temp at bearing exit at ~360°F.

No sanctioned racing body is immune to myths and misinformation, including NASCAR. There's some teams who still believe "oil is oil" and think chewing up a $4,500 gear set every race is just "the cost of racing." I know of one team who came in running 15W-50 with Bryant cranks and .0018"...

Power! They run a 0W-5 for qualifying, banking on the oil not getting hot enough in the qualifying run to cause an issue. They run 0W-16 for the race. As of Daytona earlier this year, they still do this.

That show is a joke. They intentionally do things in ways that give controversial results. This episode was a prime example. The engine they used was a worn out marine engine with thick 5/64th rings. Of course the higher viscosity helped the rings seal. Someone recently in a FB drag racing...

https://bobistheoilguy.com/forums/threads/2022-mazda-cx-9-hpl-pcmo-10w-20-7-211-miles.360267/ Though HPL's 10W-20 started with a KV100 ~1.5 cSt lower than the OEM Mazda 5W-30, they ended with roughly the same KV100 at the same fuel dilution and interval. Notice how fuel dilution increased from...

Detergents (in this sense) are focused more on prevention than cure. They come in the form of calcium sulfonate and magnesium sulfonate (most commonly), the core of which is a calcium/magnesium carbonate salt. These are the same carbonate salts found in common OTC medications Tums and Milk of...

They did nothing of the sort. Those videos came after I proposed discussion of repeated Pennzoil VOAs coming in under the 600 ppm minimum for phosphorus.

That's true. I bought concert tickets recently and cringed when putting in the card information. It was over $700 for 2 tickets that aren't even close to the stage. Front row is $1,500+/ea. A good chunk of that is stupid Ticketmaster fees. However, when they sell out in less than 24 hours...

The cost to students is insane. Meanwhile, I'm reminded that Texas A&M is paying out $76.8 million to Jimbo Fisher to sit at home.

At $27.66/hr, assuming typical 3x12 weekly schedule and filing single and 0 on taxes, she'll bring home ~$3,100 a month after taxes. Her rent is ~48% of that. After utilities, phone, internet, insurance, etc... she'll have barely anything for food and gas. That's rough. I wouldn't have a...

I was in DC for the one in 2011. I was standing in the pasta aisle at Walmart. I felt as though I was losing balance, then noticed everything was moving, glass jars of pasta sauce were crashing on the floor, and everybody was screaming and running to the exit. I had lived in California...

20% EC will clean better than 20% PCMO. I recommend using the code BITOG15FLUSH to get one quart of PCMO substituted with 1qt of EC. Run the EC with a decent off the shelf synthetic. Then switch to 100% PCMO.

I don't know why people still use Blackstone. They're the McDonalds of oil labs with Ruth's Chris pricing.

I was being metaphorically facetious as the question has been answered many times over throughout the history of this forum. I truthfully thought it was a joke or troll post. Between UOAs, engine teardowns, bore scope images, and even dyno results, there's enough information to answer your...

"Oil is oil" is perhaps the most autoschediastic phrase in all of lubrication, often proffered by those who know little to those who know even less. It's equivalent to saying "steak is steak".

That was a still image.

Rotella was tested a few weeks after Lake was in the lab shooting the video. He had to take the video down due to a copyright hit for one of the songs he put in the video. He edited out the song and reposted the video. That was the only change. I have both versions of the video.

The difference is not a significant one. The way approvals and licensing are handled doesn't allow much variance. The testing is primarily handled by the additive companies who put together add packs and base oil blends to send off for testing to that license or approval. If it passes, it's...

No. The term "pop-up pistons" refers to dome pistons. The piston has a plateau raised above the piston crown to reduce chamber volume thus increasing the compression ratio. The 289 has a short stroke which limits how much volume can be compressed. (given all other variables are equal) To...
