If you have any problem (even if it's a blown tire) use the AMSOIL Signature Series and it will help reduce this risk of blowing another tire for the time being. It will also keep your engine clean and reduce friction for long engine life. No time to go into detail. Just use AMSOIL Signature Series in any case. Also drink it twice a day
If you can't get Amsoil Signature. Get Motul 100% Synthetic 8100 Eco-Lite. It is a Dexos 1 gen2 and GF-5 oil. Not to fret because GF-6 is coming soon. For LSPI you need 91 -93 octane gasoline also. Do not lug your turbo GDI engine. No WOT until 3500 plus.
The latest thought by the researchers on the subject is the higher levels of Calcium in the oil for some reason is potentially one of the major causes of the oil. The additive companies may be dropping the calcium levels and boosting the magnesium to replace the Calcium to reduce the cause of the problem. New technology you have to love [or hate] it.
This can happen on standard port injection cars and direct injections not just turbo direct injections. fuel burns quick, low rpm engine lugging causes the fuel to ignite before the optimal timing. its not rocket science. Its basically acting like a diesel. You add more pressure to the combustion chamber by spraying super high pressure into an already small area thats already pressurized. Its more prevalent in turbo motors due to the boost pressure being added. Low octane fuel doesnt help. So high pressure = heat, high heat = faster burning of fuel, slower engine rpm = more time for pressure to create heat. pre-igntion can occur if any instance of low speed lugging.
"Best oil on the market" type of statements can be very misleading, unless you provide justification, and compare similar products. Wayde's Veloster Turbo calls for a 5W-30 engine oil. AMSOIL Signature Series 5W-30 has a Viscosity Index of 166 (higher is better); a NOACK volatility of 6.9% (lower is better); and a Total Base Number of 12.6 (higher is better). I don't believe Motul has an oil that is approved for use in emission-controlled vehicles that meets or exceeds these specifications, which are important in helping prevent LSPI.
I have a 2015 wrangler with a naturally aspirated Pentastar 3.6L V6. I get pre-ignition knock when the engine is at around 2k while going up hill. The manual states 87 octane fuel is required, but when I switch to 93 octane the knock goes away. I know the Pentastar engines have been horrible in terms of reliability since they were introduced in 2011, do you think it's wise to stick with 93 octane since the dealerships refuse to fix the problem unless you get a check engine light?
+nelson4568 Thanks for the question. First - do whatever you can to reduce/prevent the ping or knock. It will eventually destroy your engine. Make sure you are getting clean, fresh fuel, and get Top-Tier fuel if available. I'd also try Mid-Grade fuel (around 89-90 octane) and check your results. No since spending more on fuel than necessary. But what you are experiencing probably isn't the Low Speed Pre-Ignition I talk about in the video. In many cases, LSPI destroys the engine almost immediately - making it so detrimental. But as I mention in the video, the vapors from your engine oil, that travel thru the PCV system, can contribute to uncontrolled detonation of any type. Using a low volatility oil, that emits less vapors when heated, like AMSOIL Signature Series (5W-20 in your case) will help reduce this risk. It will also keep your engine clean and reduce friction for long engine life.
Short answer - no. AMSOIL Signature Series oils are formulated from the highest quality base stocks available for automotive oil. This gives them a higher viscosity index rating (which measures the oils ability to resist thinning when hot), and Signature Series oils also have a lower volatility rating (which measures % of evaporation when heated). AMSOIL XL and OE lines of oil are very high quality, but they can't match Signature Series. If I had a turbo gas direct injected engine, I'd use Signature Series. If you live in a warmer climate, I'd even consider moving to the 10W-30 grade Signature - it has even better numbers on the volatility, which contributes to LSPI.
I own a veloster turbo (1.6T gdi). These cars have seen random low mileage catastrophic engine failures (as reported on forums). I wonder if lspi caused the failures?
I don't have the details, but if they are turbo gdi, LSPI could definitely be a problem. Modern engines rarely fail, so it has to be something drastic. I'd definitely use an oil that has a very high Viscosity Index and low volatility rating. These oils are more stable and less prone to contributing to LSPI. AMSOIL Signature Series fits this description very well.

Best information I found on the subject. Thanks
+Dário Barreiro Thank you!

Informative video, thanks.

Wayde try Motul, its the best oil on the market.

I use Amsoil 5w-30 xl in my Veloster turbo!!! Is its at good as Signature series??

Lspi occurs on both automatic and manual transmissions?
Not certain, but I would assume yes. Transmission should not make a difference.
Depends on the shift point habits of the manual transmission driver and the shift point parameters of the ecu for the automatic car.

I just take my car to the dealer for oil changes. I think they use quaker state synthetic.
Modern subaru engines still fail frequently
