Glittery Oil
#21
Please let me in on the joke....what's wrong with Mobile 1 Synthetic? Or what was it that I wrote that is amusing? As far as "not pushing it" I'm talking about RPM. I find the car is quicker shifting at about 6800 and since I'm on a stock damper and stock head revving over 7k is not only not productive but invitinf oil pump,failure.
So....what???

Yes, Ben. We're taking the thread there.

FWIW all Schaeffer products seems to have wild price swings on amazon. Throw your desired item into a price history website to make sure you aren't overpaying if you go the amazon route. I use their Moly EP additive and it ranges from $6 a bottle to ~$15. Their oils seem to do the same, $30-50 a gallon for the same oil.

The Mobil 1 10W30 would be fine in a lightly stressed engine for as long as most original owners have them. The forces we are putting on the engine's narrow bearing surfaces are two, three, or four times as much from the increased power depending upon if you are at 200, 300, or 400whp. The engines weren't factory designed to do it. The viscosity of the T6 being 40%+ more or the Schaeffer being 80% more becomes important quickly. If that film strength does break down under the force you then need extreme pressure (EP) lubricant additives like zinc and phosphorus to continue to protect from metal to metal contact.
I also noticed Rotella T4 (EK4) in my searching and though it had a really great additive package and decent visosity it had a 204*C (399*F) flash point, which would preclude me from considering it.
Like I said, there are several good oils out there for what we are doing to these little engines. Do your own research and understand why, then find something that you like.
TL;DR - Mobil 1 10W30 is too thin and lacks enough additives you want for trubomiatas, imo.

This is good information. I imagine that I'm not the only one that thought I was doing the right thing using Mobil 1. Looks like my next oil change will be early and go to a heavier weight. Glad that I never succumbed to the 5W30 and at least stayed with 10W30. Time to research what I'll use instead.

After reading up some on oil, it looks like Amsoil would be a good choice. Any recommendations on the weight that I should use? Northeast Florida, fifty degrees is cold here and summer is like Florida....in the 90's. 10W40? Help me save my engine until I can get the new one built.
FMII @ 12 psi VVT motor with stock internals. Good cooling and conservative tune.

I now use 50 weight as the top number.
More recently on track it has reached 250*F oil temp since I turned the power up. I need a little bit more cooling or the discipline to lay off the "high boost" button until then. I lack discipline. And it is a very shiny button.
For street at your power levels 40 or 50 for the top number would be much better than 30.

Thanks to all who replied to my questions. I'll be going with Amsoil XL 10W40. I've switched off the EBC and running wastegate pressure until I make the change.
i notice the Amsoil site mentions 12,000 mile oil change intervals....really? I've been on a 5k regime since I bought the car.
