Here's is my 2 cents, revisiting this thread as I was asked to by a member to comment here:
Sorry, and no offense, but the Castrol edge is at the very bottom of my list that why you 'need' the lucas, which I will pass on as well in this car, but I use it in a low compression pushrod motor like my truck-the lucas is good for older motors loosing compression, its thick stuff,and the Edge is a no go in my book, its got a VI of 166.
I also dont see the VI on the Pennzoil as worth buying in the 180s, but its a great oil if you get the top pennzoil product, is that platinum or ultra, I forget, and dont really care.
If I am gonna go that low in oil quality, I am on the idemitsu, its cheaper than motul or eneos, and far better than anything at walmart-none of that belongs in my 12.6:1 motor that is getting FI. even in a NA motor, nothing can hurt from using a top notch oil.
All oils are not equal. Thats like saying store brand soda, c&c, coke and pepsi all taste the same, they do not. Cole is the real thing, the one that ste MJ's hair on fire, the one they all imitate.
For motul, the eco lite 8100 is sweet. Good stuff.
Sustina is in my motor this very minute, which is on a dyno now.SUSTINA W BASE base oil has an ultra-high viscosity index (229 in 0W-20), try and top that. No its not cheap.
Redlines base stocks are no match for motul or eneos, no boron, as weak as AMSoil if you ask me. Sorry again, not an AMS fan. Please dont hate, k?
I dont think it is about my opinion, or yours, while you can use whatever cocktail you want,whatever oil, and flo rates, the engine was tested an built at the gunma plant on Subaru oil, what you fill it with there after is on you. I like the SM but am betting it comes with subarus' new SN that I dislike, but its not bad oil at all. Its idemitsu SN. Not a repeat in my garage, but for inexpensive back up oil, it okay to keep one sitting around.
I buy mine
here since the nearest dealer is 45 minutes away, good to keep at the house thanks to the UPS guy when I am not planning a trip to PHX pr FLG in the near future, as was proved while I was testing an oil cooler and a unclamped line blew off, good to have extra sitting around. I was out of the subaru SM, which is my DD oil. I setup up to motul 8100 and sustina for track use since they are banging formulations with stellar VI. I am not here to debate why or whether VI matters, so not trying to start a debate. As I said, I'm chiming since a member asked me to share my thoughts.
what I like or what you use and like, really doesnt matter- this is chemisty, its about VI, and flow rates, and wear packs and base stocks, not who likes what football team-this isnt a fan sport guys.
I'm not able to subscribe to the using thicker oil is better camp. you get more wear using the wrong oil. fact, and have yet to be convinced by any data otherwise. what joey does at the track is niether here or there. No offense if your name is Joey!
these arent yesterdays motors or dino oils from the 70s that break down with heat. you do more injustice running too thick a synthetic oil, the right oil i sthe right one. simple, track, dyno, whatever, use the best oil you can afford, that is my advice. most good oils run $8 to $11 bucks usually, unless you find a deal, but I havent found motul or sustina for less.
You should know that. use a good oil, and change it out between 5k and 7500 depending on usage, and you will be well within the oils performance limits, most oils can go further yet.
there is a reason good oils like motuls, sustina, and dealer oil, costs what it does, you get what you pay for when buying oil and if youre able to select group IV technology, blends that have the best packs will get you the most power, best mileage and least wear.
