Because the honda 1.5T is using low tension piston rings. These rings much easier to get stuck with just some carbon.

True also what. unless you buy from Vanli Jln Ipoh and keep a spare at home, which u can do blind test ( by smell ) , other than that, technology nowadays can produce fake stuff at almost nearlee quality

So bro how's the oil? Seems tht VRP, good for LSPi T engines;
Your driving style is considered "severe service," and here’s why this oil is an excellent match for those conditions.

Why Stop-and-Go Driving is So Hard on Your Engine:

1. More Frequent Low-Speed Pre-Ignition (LSPI) Risk: Your 1.5T engine is constantly accelerating from a stop (high load at low RPM), which is the prime condition for LSPI—a major killer of turbocharged engines. Valvoline Restore & Protect is specifically formulated to protect against this.
2. Increased Fuel Dilution: In short-trip driving, the engine rarely reaches its optimal operating temperature for a sustained period. This can lead to unburned fuel leaking past the piston rings and contaminating the oil (a known issue with direct injection engines like yours). This thins the oil and reduces its lubricity. A robust synthetic oil resists this breakdown better.
3. More Engine Wear: Most engine wear happens during cold starts and at low operating temperatures. Your driving pattern consists of many "mini" cold starts and prolonged low-temperature operation.
4. Heat Buildup: Sitting in traffic with the engine running creates significant heat without the strong airflow from driving at speed, putting stress on the oil.

How Valvoline Restore & Protect Specifically Helps:

· Superior Anti-Wear Additives: The "Protect" side of the formula provides an extremely strong film strength that protects engine components even during the frequent low-RPM, high-load acceleration of stop-and-go traffic.
· LSPI Protection: As mentioned, this is its flagship feature for turbo engines and is perfectly suited to your driving style.
· Thermal Stability: It resists thinning out and breaking down under the high heat loads generated in traffic.
· Cleaning Power: It helps prevent the formation of sludge and deposits that can be accelerated by fuel dilution and frequent short trips.

Crucial Recommendation: Shorten Your Oil Change Interval

Given your "severe service" driving conditions, the most important thing you can do—even more important than the brand of oil—is to change your oil more frequently.

· Honda's "Normal" Service Interval: Might be around 10,000-15,000 km.
· Your "Severe Service" Interval Should Be: Every 5,000 - 7,000 km, or every 6 months, whichever comes first.

The restorative and protective additives in the oil get used up over time. In your demanding driving environment, they deplete faster. Changing the oil more often ensures those additives are always fresh and active, protecting your engine.

Final, Tailored Recommendation:

1. Product: Valvoline Restore & Protect High Mileage Full Synthetic 5W-30. The extra seal conditioners and anti-wear additives are ideal for your high-mileage, high-stress driving.
2. Interval: Change it every 6,000 km. This is a safe, effective interval for your usage. Don't wait for 10,000 km.

By using this high-quality oil and adhering to a shorter change interval, you are giving your Accord's turbocharged engine the best possible defense against the harsh reality of daily stop-and-go traffic. This is the perfect strategy for long-term reliability

As read from another thread discuss about engine oil, we can only know if the engine oil are indeed good by oil analysis taken from the used engine oil, where a through details, parameters are shown.

Picture taken for my x70 ckd, which use stock engine oil from Proton SC, from new till warranty ended. They use Shell Helix Ultra 5w40 for 5L.

Mileage taken at 93k km

Yeap, UOA is good analysis. BITOG is EO kitab suci.

Nice, every 10k km serviced or earlier?

10k km interval. on early days (thanks to MCO) car was average 3k-4k per 6 months for service

Synpower is the best Valvoline oil.

My honda no oil consumption problem..... 10k interval serbis.

Looks very clean so far, for your driving style n changing in 10000km, this looks ok. How many km per month? City/highway ratio?



Just wondering this part is it varnish or leftover engine oil? Based on the shape, it looks like varnish. Anyway the most severe part will be at the piston ringlands...since that is hottest.

my cars all 10k km service interval
all full synthetic, using 5w30 and 0W20

So pic taken ,did gasket change?

People did bring the valvoline restore n protect for oil analysis before. The oil nothing special, even the detergents are just normal values compared to other fs oil.
However already many reviews said it works in helping reduce blowby and oil consumption s, in forums and youtubes all got document their findings. Valvoline engineer said they have special formulation in their addictives, however the oil analysis will look normal only unlike their first version of vrp which uses lots of ester to clean super aggressively until it clog up the oil filter too fast.
If u have abit of varnish in your dipstick, u just need to see the dipstick gets cleaner.

so valvoline is the best ?

well time to get it for my 12 year myvi

It might be me just being bias, but my engine slight ticking noise seems to get quieter after 500km? Im not too sure since its just 700km so far. My engine inside looks super clean since i always change 5000km, so cannot use sight to check also.
I think most obvious thing i can check is my oil consumption rate since i have been monitoring it since last time. Currently 700km i cannot see any changes in oil consumption so far. Previously using 5w40, now is 5w30.

yup, got very slight leaked at one location of the gasket. so change it.

if for me, any original genuine engine oil fully synthetic, followed the car oil viscosity receommended are the best. Some newer car (or since 2015 onwards) did recommend for 0w20 oil for greater FC and "lighter" feeling from the engine

Haha so short intervals, so no need restore also.
I plan to also get it soon as price same/cheaper as getting Honda Ori oils

Normal wear n tear fr valve gasket leaks once hit 100k km+

I did changed to Shopee Mall engine oil which they advertised with PAO + Ester. If it indeed clean agressively (due to PAO + Ester), I will repeat this.
Is this bold parts are similar to Shell Helix Malaysia version where they advertised it as "Untuk Pasaran Malaysia" where most known no technical changes for the oil vs other region.

For analysis parts, hopefully there are one who done it on the Petrol version. Cz some brand advertised their Fuel are the bestest vs others, some mentioned put double additive vs recommended, while some offer the best for their 97 Ron.
