What oil is best? and what ratio?

[Tomos770]

And unburned smells like strawberries and burned always reminds me of cotton candy but my nose is jacked up from working in a petrochemical facility so it could be strawberries.

It smells LIKE strawberries for the first 5minutes....after that smells like burnt plastic to me

I've seen many of these wonder oils over the years. You really think some guy in his garage stumbled onto something big the oil companies don't know about?

Really like the we don’t use a dye because if your having wear issues we want you to see it. The reason they rebuild motocross bikes all the time isn’t because they don’t run anymore it’s because they lost that minute amount of power and the want it back. If your seeing metal in your undyed oil residue in the engine your probably already done. Her and a thermal engineer came up with it, wonder if they hired a tribologist to blend the oil for them. Like she added in the we use friction modifiers and grade modifiers ect just like every other oil on the shelf does. Looking at the temp gun and it’s 20-30 degrees swing it’s pretty hard to judge anything by that.

Right now it’s Ipone Scooter semi-syn at 32:1 JASO FD - it’s on the JASO certified list - not a “meets the requirements” oil. And unburned smells like strawberries and burned always reminds me of cotton candy but my nose is jacked up from working in a petrochemical facility so it could be strawberries.

I have a lot to use up- Motul 800, Castor 927, Honda HP2, Red Armor, Husqvarna XP and Klotz Techniplate. Maxima K2 is on order. As an old amateur motocrosser I’m partial to Maxima - especially since Belray sold out to Calumet.

He’s only smelling the oil

I still stand by my comment.
As it pertains to MX bikes. I raced and rec road them for years. You rebuild them often because the piston to wall clearance opens up and you risk cracking a piston. If your doing it right you rebuild long before power drops off.

Perhaps he should consider pursuing a degree from https://achs.edu/programs/online-master-of-science-in-aromatherapy/ Them weirdo/niche jobs are often quite lucrative.....$$$$$

Or maybe it's better to say that it's a paid product advertisement

They got Thermal Engineer,lol

 

[pbillyi69]

im a thermal engineer too....its hot dont touch it or you will get burned. its cooled off. now you can touch it.

 

[Partner]

And he'll touch you anyway to check if you're telling the truth

Saber oil update ,the images i posted earlier were after a bunch of limbing ,about 8 trees worth ,very light load maybe 1/3 throttle blipping the limbs off ,i bucked 3 trees into firewood last night ,shut the saw off after a wide open cut without idling so i could see the plug loaded ,is much cleaner when loaded ,but the edge is still sooty ,and the muffler can still has some soot like a wood stove pipe would get ,the mobil 1 did not do this or the 2 r yamalube when i looked inside ,anyone have explanation why saber leaves so much soot behind ?View attachment 5029 View attachment 5030 View attachment 5031 View attachment 5032

pics attached - this was after 3 or 4 tanks I think. I have 11 or 12 now.

I think this weekend...

- I have a 661 only run on schaeffers 32:1 6 or 7 tanks run only with muff mod
- I have a 661 only run on honda hp2 32:1 11 or 12 tanks run only with muff mod

like to find the time to take the jugs off and see what things look like.




watch your temps. I think this stuff ran the hottest for me. but I was ru

You are describing pre ignition, which octane doesn't prevent. As you mentioned your timing was too far advanced.
I run premium E Free or Canned fuel because it's gives you a cushion for volatility loss induced octane degradation and is insurance if you have a high load lean excursion.

I'm just an ignorant consumer with 68 years under my belt. I ask you.... if octane does not prevent pre-ignition why does Valvoline say this?...

LOW-SPEED PRE-IGNITION PREVENTION​

While the causes of low-speed pre-ignition are not fully understood, there are a few critical steps one should take to prevent it from happening. That includes selecting high-quality engine oil, high-octane fuel, and cleaning products for a petrol system.

Poor lubricant selection leads to a wide range of engine performance issues. One of them is low-speed pre-ignition (LSPI). Also termed stochastic pre-ignition (SPI)...

Pre ignition and pre detonation are two different things, I think?

Im not sure why valvoline would say that. You will find much bad info on this subject on the internet. The refinery I work for even does this as well.
But that doesn't change the fact that Octane is a measure of a fuels resistance to Detonation and that pre ignition is a completely different phenomenon and the Valvoline article mentions this.
The recommendation for the use of high octane fuel in a GDI engin to help with pre ignition is probably with the though that if the engine is in slight detonation its also running hotter piston temps and that high octane fuel may qwell the detonation and lower pistons temps, which would make pre ignition less likely. This is fubar logic as modern engines, and a GDI is a modern engine, have knock sensors that detect detonation and dials ignition timing back accordingly. They also have EGR which lowers combustion chamber temps. Overall the article is just poorly written.

Confusing Detonation And Preignition

Preignition destroys immediately, detonation wears by degree. Knowing which wrecked your engine will give you a clue to what to fix.

Pre detonation isnt a thing. Its a bastardization of the words pre igntion and detonation. Detonation occurs well after the plug fires so there is nothing "pre" about it.

I was taught that cars had mechanical accelerators in the ignition device, but in small devices this is not the case - the ignition is accelerated, which is why lower rotational speeds of these engines under load are unfavorable.

The ignition of a car or a chainsaw is the same in that they bith have an advance curve. Wether it be mechanical(old cars) or electronic.
