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 ***.

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.

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.

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

Its not helpful. Mobile-1 0w40 is the ****. 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 ******* 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!

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 ****, I am the ****, and that's that. The person you should be questioning is gayus69, who is more full of **** than you are, claiming to run harder and longer on the street than I rail your sister.
