Cooking oil?
 

Currently I am running a stock engine. However, after running on full throttle between 5k and 7k for about an hour and half or more the oil pressure tends to drop to around 15psi at idle. The pressure drops, the lifters start to tick heavily and the oil turns rather dark. Does this sound like cooking oil?

Its not cooking, its just getting really hot. Probably need an oil cooler. What were you doing to hold revs that high for that long?

I just ordered the FM thermostatic oil cooler. To keep the revs that high I simply drive fast in the santa cruz mountians, or the coastal range, or the trinity alps, or the siskyous, or the mountains in northern oregon/southern washington.

I find that the weaknesses of a stock(mostly) miata are brakes and a engine compression. The compression would be nice both for power and for braking. The problem is that running at 8 or 9 tenths for hours tends to overheat the brakes, the oil, and the gearbox. No worries though.

What weight oil? Go with thicker but let it get hot before beating on the car. My car is running a blend of 10-40 and 20-50 and sees 80-90psi when cold but when warms up comes down and works great and no more lifter tick...EVER.

Please explain the mixture!!

Tried running 20-50 and it was showing to high pressure and went to 10-40 and it was taping a little when very hot so 2 quarts of 10-40 two of 20-50 and its been great. Been about 1.5 years with this "mixture" and seems to keep the 150K mile 15psi motor happy.

whats the average temp like in VA Beach, I might want to give that a try. BTW a 13.7 with 200 whp seems kick ass.

What year is the car? Synth oil? You should be fine doing mountain runs becuase you can't really drive the car hard enough on the street or mountain roads to need the oil cooler.

No details on OP's oil. No details on water temp. No details on OP's car. Is it a 1.6 or 1.8?

It would help to know because the 1.8 has an oil cooler.

Please be much more vague next time. It makes it much easier for us to give the incorrect advice you desire.

Summer 90-100 winter car does not go out much.

Thanks!

You do realize that the viscosities simply average, right? Anyhoo, you could try a racing oil. Have to agree with Hustler, though, riving the car on the street really won't generate THAT much heat in the grand scheme of things.

It works.

Why will a ZDDP pack and lack of detergents increase viscosity?

Well i'm disappointed. I saw the title description and i was hoping to see some grewsome pics of what happens when you put "cooking oil" in your engine.:noob:

Just throwing it out there that racing oil may be better suited to his usage of the car than regular motor oil. May not be. Dunno. Also pointing out the fact that blending (let's just say) half and half 10W-40 and 20W-50 results in a 15W-45 blend. Given this fact, it may be better to simply select an oil better suited to the situation. Even though I think the situation is being highly exaggerated. Kind of like your masculinity. :fawk: :giggle:

Than that is my answer, run 15W-45, works for me.

Its not helpful. Mobile-1 0w40 is the shit. Rotella and Rotella synth are better in some respects. You should probably do some research before you recommend any oil because on a scale of 1-10, you don't have a fucking clue about engine oil, and you're a closet homofag.

I'm worried! You mentioned Oregon & Southern Washington there. No way I want to be anywhere near you running the car at 8-9/10ths for hours on end on public roads. You are either completely full of crap, have no idea what 9/10ths driving is or you are a complete menace to society.

Enjoy your fiery death at the bottom of a canyon. I just hope you don't kill some nice family in a minivan while you were at it. I hope you remember this post while your skin crisps.

And thanks for coming back to your thread and answering the questions of all the people here trying to help you. Oh wait, that's right, you didn't! :vash:

Wasn't really making a recommendation, just tossing something out there. If you weren't constantly beating your 2" dick to a photo of Tom Cruise sitting in your mother's basement, you wouldn't be so up tight about things. BTW, Mobil One isn't the shit, I am the shit, and that's that. The person you should be questioning is gayus69, who is more full of shit than you are, claiming to run harder and longer on the street than I rail your sister.

Oh, sorry it took me so long to get back to you. See, someone was talking shit to me like a bitch and I had to murder them in the street yesterday. This all stemmed from me getting out of my personal helicopter that I use to avoid traffic because, well, I'm far too important to sit around in traffic and shit like a peasant. Anyway, as I was getting out, I saw this gang of street thugs jacking with a couple Victoria's Secret models and I had to snap a couple necks for the rest of the gang to get the point and run away in terror. After that I ended up taking a few of the models back to my penthouse where they took turns making passionate "lust" to me. Unfortunately I had to leave in a rush though because Flavio Briatore invited me to spend the weekend on his yacht because some of his model friends were in some relationships that weren't working out and he wanted me to "show them what it was like to be with a man," and I lost the # to the valet downstairs so I couldn't contact him to pull my 599 around. So basically I was late to the airport, but now I'm in the Gulfy and replying to the thread you've turned into shit. So please, keep talking shit. I'm far to busy and important going through life as a the definitive international, ultimate, universal desire of all women.

Gulfy? Real men like me jet-set in personal fucking 747s. I'm feeling kinda cramped in my jet, though, but my 787 is fucking late on delivery. I don't have to snap necks for people to get my point, I just have to walk into a room and wannabe thugs like you curl up in the fetal position and beg for their lives like the bitches they are, while their girlfriends all beg me to "have my way with them." I never have to call a fucking valet, I plow a bitch and then send her ass to get the valet while I fuck her best friend. Then I get her ass back up to the room and have a fucking threesome while the valet waits, and I just toss a fucking stack of benjamins at him when I finally feel like leaving. The biggest decision I have to make every fucking day is which continent I'm going to fuck my bitches on.

Oh, and that yacht you were on? That was my fucking dinghy before I sold it to your friend's sorry ass. After I defiled every square inch of it twice over, I decided I needed something bigger to tow behind my fucking cruise ship.

Go back to masturbating in your Gulfy and imagining that you were me, Mr. Weaksauce.

2 Hustlers!?!

god help us all

I thought cloning humans was illegal!!!!

I was thinking some one finally ran cooking oil in a miata :)

I know they do it for diesel engines a lot.

Imagine driving around the mountains smelling like a french fry cooking machine at mcdonalds :D:laugh:

Just think of the possibilities. You could almost turn the miata into a rolling chicken nugget machine.

Put baby chickens into compressor side(chicken mulcher)
Combustion cycle, coupled with running cooking oil, fries em up
and a healthy 3" free flowing exhaust spits em out!

Nice and fresh! Just the way i like it.

hehe i got mr fusion to power my flux capacitor, i'm good to go.

mobil one is pure garbage eversince about 2003 when they changed i only run royal purple or amsoil now. A 20-50 is also great if you perform in hot weather, it doesnt break down as easily. Inevitably the problem you are havingis on i have lived with ever since i went turbo. Its a problem of oil quality as much as it is a plausibly weak relief spring and, the temperatures. Amsoil and Royal purple actualy last for me though so i suggest you try one or both of those.

How many miles are you doing on Amsoil, or Royal Purple.

Rotella son! I don't like the synthetic at all. I gave it another few thousand miles to see if I changed my mind. HLA noise is terrible, its far too thin for my liking. I'm going back to the regular Rotella tomorrow. I bet my HLA goes away and stays gone for at least another 4,000 miles. After this run of Rotella I'm going to try Delo 400 for my curiosity.

I first thought this thread was asking if one could use cooking oil as an engine lubricant.

i get about 3k where as other oils i wouldnt even get over 1k in the case of mobil junk i would get maybe 300 miles.

Wow, seriously, i use mobil 1 10w30 and get about 3k before i start to hear the HLAs faintly. then i change the oil. And what do you mean before they changed? Should i be concerned about mobil 1?

Pay the 20 bucks or whatever to get an oil analysis done to see what's actually going on in your engine with your setup and usage. Anything else is just guesswork based on other peoples' setups and driving habits, which are likely to be totally different from yours.

here's that nasty 0w40 Mobile1 that everyone thinks sucks:

here's 5w30 M1 for a comparison:
Attachment 203734

Here's a comparison Royal Purple which i found:

...its not exactly a bad oil but I'd like to see more ZDDP for the price. Although we don't have TBN#s for each oil, its fairly obvious that PenPlatinum is the bomb

Here's Rotella Synth which I use for obvious reasons, and its $20 per gallon:

You guys with lifter noise need to pick an oil that holds its viscosity at temp, which resists shear from the turbo, and lives enough to justify the price. Diesel oil is the way to go in a turbo car, period. Even dino, $10/gallon Rotella T outdoes the expensive oils in the #'s that matter.

Hustler,

Been running Rotella synth since the last big discussion on oil here maybe 8-10 months ago. Looked at your info and research over at bobistheoilguy. Rotella FTW. When I get my new valve seals in, so I'm not using oil like it's free, I'll post up a uoa.

Sad all the guys that come in as Hustler wannabe's. Gotta keep that pimp hand strong.

I don't understand how you guys are having good results with the Roro synth, and I have such horrible HLA noise with new HLA's and a fresh rebuild. I can drive it normal, 20 miles of stop and go, then let it sit and idle for about 5 minutes and it sounds like a pea thrasher. Its hot out, but its not THAT hot, and I don't drive it hard enough to ever get it over about 3/8 gauge on temp.

They sold the company to someone else in like 2003 man so yeah its not near as good as it was. Hustler i will go over your "charts" and get back to you on that shit.
