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.

Lspi occurs on both automatic and manual transmissions?

Best-Synthetic-Oils.com commented on 18 Nov 2015

Not certain, but I would assume yes. Transmission should not make a difference.

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

Best-Synthetic-Oils.com commented on 05 Dec 2014

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.

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

Best-Synthetic-Oils.com commented on 28 Nov 2014

"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 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?

wayde philpot commented on 22 Nov 2014

I just take my car to the dealer for oil changes. I think they use quaker state synthetic.

Best-Synthetic-Oils.com commented on 22 Nov 2014

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.

it's either apocalyptica (finland) on four cellos or fourplay (aus) with cello 2 violas and a violin. i'd guess apocalyptica but.. aussie vid, aussie artist?
