30,000th km Service

AHW308 has done almost 30,000km and ready for the scheduled service/maintenance. Will be sending to regular SC on Monday Sept 27th. As usual I will BMO oil and my choice is Mobil-1 Gold*. This time got FREE umbrella [or Lap-top bag]...
[*Mobil-1 Gold 0w-40 membuat enjin terasa lebih mantap dan solid pada red-line berbanding pelincir 0w-30, 5w-30 dan 10w-30]

Pre-Service Inspection
As usual I did my own inspection prior to sending the car for servicing.

Tyres:
New tyre thread depth = 8mm
Average remaining thread depth is 4.175mm
so, sudah makan 3.825mm/30,000km or 1.275mm/10,000km.

If wear limit is 2mm, the remaining usable thread is 2.175mm, i.e lasts another (2.175/1.275)* 10,000km = about 17,000km (making CSC3 tyres to last beyond 45,000km)

Brake Pads:
Front Bakepads sudah makan about 2/3. May require replacement during next service @ 40,000th km. Rear brakepads only gone 50%

my308 uses Mobil1 ow-4o 'Gold' and RON95 fuel

For the first 10,000km I'd been using 10w-30 [?] oil but it took time for the engine to warm up and stabilise on first start in the early morning; when hot and pushed beyond 180km/hr the engine seemed to be sluggish. I was thinking whether it would be wrong to change the weight to 0w-40? I believed the turbo would run better when hot and I definitely need the engine to warm up quicker in the morning but have good protection at the same time, especially for the extremely hot turbo.

I was recommended personally by a researcher during my visit to a research Laboratory in Karlshure near Frankfurt last summer to use Mobil 1 0w-40 'Gold' [5w-40 also can, but not available locally]. It is designed for new generation of turbo engines and can be used effectively - will provide outstanding low temperature flow and outstanding high temperature protection for the turbo as well as for the engine.

It could be due to the right choice of the oil that made RON95 fuel economy and performance is as good as RON97! Been running the car on Mobil 1 0w-40 'Gold' [RM300++ for 5 liters] for more than 5000km now.

Pls continue to read my previous postings on drive-tests my308 for fuel economy and performance running on RON95 in combination with Mobil-1 0w-40 'Gold' oil.

Which Oil and what Viscosity is suitable for 308Turbo?

This is another burning question. Well of course in the first place the oil must comply with ACEA specifications and have the right viscosity rating [forget about API specifications for EP6-series engine, leave the American Spec alone! 308 engine is European].

The engines rotating parts are protected from heat and friction by a thin layer of oil. Understanding the viscosity ratings and detergents used in today's modern oils is critical to keeping Peugeot 308 Turbo engines running effectively/efficiently.

Now what does viscosity rating [e.g SAE 30] mean?
Viscosity refers to how thick or thin the oil is. The temperature requirements set for oil by the Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high).

Many ppl think that multigrade oil [such as 5W-30] thins at low temperature and thicken at high temperature. WRONG. The oil always thicken at low temperatures and thins, i.e more fluidity at high temperatures.

Then what does 0W-40, 0W-30, 5W-30, etc. means?

For instance single grade oil, such as SAE30, SAE40, SAE50, etc. thicken as honey when freezing cold and thins like cooking oil when hot. It looks ok to use this grade of oil at operating temperatures but hardly flow [unusable] when cold. Now take a look at oil with SAE5 or lower. This oil grade will thicken like cooking oil when cold but thins like water or alcohol at operating temperatures, i.e suitable for low temperatures but loss lubricating property hence not suitable when hot.

Now seems that the engine needs two different viscosity grades [SAE] of lubrication for starting at cold temperature and another one grade at operating temperature.s What about the intermediate temperatures during warming up? Nah, now it looks like the engines need several viscosity grades of oil for different engine temperature.

Hence MULTI-GRADE OIL such as Mobil 1 0w-40, Syntium 5W-30, etc. were "invented" to meet certain low temperature and high temperature requirements simultaneously.

By adding polymers to regular or synthetic oil, chemical engineers can produce an oil that has variable effective viscosity grade depending on its temperature. Before the engine warms up, the polymers contract and float around without purpose. As the engine reaches operating temperature, the polymers expand to ensure that the oil's viscosity will not fall beyond the lower grade rating.

The worst routine engine wear occurs when we start the car. All the oil is in the oil pan, instead of being distributed throughout the engine and turbo. If we used a very thin oil, we could quickly pump our engine its lifeblood through those tiny passages. However, by the time we just about to engage 'D' or the 1st gear the oil would be too thin to separate the pistons from the cylinder walls and we have a seized piston.

The multigrade oil is the answer to our prayers. We get a relatively thin oil for our startups and warming up and a higher relative weight when it's "hot" (i.e at the engine operating temperature).

Peugeot Australia recommends 0W-30, 5W-30 oil for Peugeot 308 petrol engines.

Oil for 308THP

It has been quite long time debated on which lubricant is suitable for 308THP. I only choose the one which comply with the engine requirement to endure my driving styles.

It could be 'crawling' at speed limits using auto-cruise for economy/leisure driving or flooring the accelerator on second and third gear up to 115kph and 160kph respectively when got spirited along winding federal routes, or storming at 180kph on wet expressways or beyond 200kph on fourth gear when it is dry, straight and flat....

The lubricants were tested to the extremes. I'd got the apportunity to witness THERE with my own eyes and mind.
I use 0W-40 Fully Synthetic Oil which comply with ACEA A3 - i.e Stable, stay-in-grade oil intended for use in high-performance gasoline and direct injection engines. This oil is however not the best for the cat. converter though. In such case it needs ACEA Cx - The C sequences are roughly based on the performance criteria of the Ax/Bx sequence but with chemical limits. To meet Euro IV emission regulations - nothing to do with the engine.

Mobil1 0W-40 for instance exceeds industry standards and the major leading engine manufacturer requirements. Mobil 1 0W-40 keeps performing well after conventional oils cannot. Mobil 1 0W-40 provides the widest range of protection providing the extreme cold start protection of an 0W grade and the high temperature protection of an SAE 40 grade.

According to Nassim Marketing Manager, the official statement from Peugeot for the 308 engine oil is 5W-30. [Nassim service booklet could have been printed in error]. I would like to add that the oil shall also comply with at least ACEA A3 and C2 specifications. API spec is insufficient for the new generation EP6-series prince engine.
