1G Amsoil Dominator 10w-30?

[05Nissan350z]

Hey everyone about time for an oil change, I was running Amsoil signature series 10w-30, and was thinking of going with the dominator series this time or possibly a different series.. My dsm is a 91 6bolt awd and had about 300-350ish hp. It's my DD just wondering what you think on the dominator series or If I should run a different weight etc.

Their dominator is good stuff! According to the research forced performance did http://store.forcedperformance.net/merchant2/graphics/news/Forced Performance Recommendations for Motor Oil.pdf
it has a zinc% of 1575 and a phos% of 1424

I'm currently running Valvoline vr1 conventional, Because of its high zinc/phos percentages I've never had any catastrophic turbo failures with it, but i have noticed that it will get nasty black in a short time period. I was going to go with their synthetic brand vr1 to see if it improved, but that can only be bought online so i figure since i have to order my oil online I may as-well make the switch Amsoil dominator for a couple $ more.


Amsoil only makes 100% synthetic oil's. With Valvoline there is approximately a $6 difference between their non-synthetic VR1 and the synthetic VR1 racing oil. Valvoline conventional can be picked up at your local O'reilly or pep boys for about $7 (But only in straight 60 grade or 20w50) Their synthetic vr1 oil can be bought online/eBay. if anyone is looking to go with 10w30 vr1 take note that the zddp levels drop to 1100 (not mentioned in FP's research)

I have also noticed how nasty the oil gets quickly, and i change my oil every 750-1000 miles for that reason. I like the conventional.

^750-1000 miles?!!?! holy crap, I'd change my oil every week in that case! . but assuming you don't drive yours much, it's reasonable.

No i dont drive that much. I only have 13000 miles on the motor since the spring 2012 it seen the track in it's life probably only 20 times

I've been running the Amsoil Dominator 15w50 in my car now for over 1000 miles and it has yet to go turn black. The 15w50 is a little thick for Arizona winter conditions in my setup. I would typically see around 25psi@ idle but now that the weather is starting to heat up i'll see 15psi @ idle which I'm more comfortable with, so if this stuff works out through the summer with no turbo failure, I'll just run 10w30 in the winter and 15w50 in the summer.

I was however able to find the 10w30 and 20w50 syn Valvoline VR1 at autozone, but it was one of their main hub stores that is open 24hr's. The regular hour stores surrounding me only carried the conventional vr120w50.
