New Bridgestone Adrenalin RE002 for Subaru MY08 WRX

After 40,000 plus thousand KM of use on my Bridgestone Adrenalin RE002 tyres they are at end of life with only a millimeters of tread remaining.  My last set of Bridgestone Adrenalin RE002 tyres were purchased around 14 months ago during a buy 3 get 1 free offer and I wouldn’t have been able to justify the cost without that deal. I absolutely LOVE these tyres they grip so well in all conditions. Before buying my first RE002’s I bought a set of 1/3 used RE001 and that started my passion in tyres. The tyres do also have a very nice tread appearance as shown in this photo of the tyres sitting in my garage before were fitted.

Luckily the price of these tyres have come down in price dramatically.  Now I can afford to buy all 4 tires in one go and they will cost me the same price I paid for 3 last time. Before I desisted to buy the same tyre I performed some research and found this post by RexandRegina on the WRX AU forum.

 

A summary of tread wear rating – lower values generally = better grip; higher values = longer tyre life.
Tyre wear ratings – these are a proxy for grip, where the number is lower the tyre will wear more quickly usually due to construction from a softer compound.
However, tread design may reduce contact area and thereby reduce dry grip but improve wet grip. Also the overall construction of the tyre will have an impact. Be aware of speed, mass and temperature ratings.
100 = the value attributed to the life of a test tire; thus a tire with a value of 200 will last twice as long as the test tire.
Value (generally lower values equal better dry grip)

Before placing my order the tyre shop informed me that they didn’t have any stock of the RE002 and perhaps I wanted buy the S001 instead. I read the post and found the S001 is as grippy as the current WRX tyre which isn’t as grippy as the RE001. So I inform them I wasn’t interested and to order in the RE002. They told me that they are on back-order and there is only 2 in the country. Its been 2 weeks since I ordered them and I’m still waiting. But the RE002’s are worth the wait.

Brake pad replacement time for MY08 WRX

Black Betty my car now has around 108,000KM on the clock. At its last service my mechanic informed me the front brake pads need to be changed next service and the rear pads will need to be changed in the not so distant future.

I started investigating which aftermarket products are good for my WRX. Everyone had both positive and negative feedback about any given product. After much time spent with no clear answer I decided to get a quote from my local Subaru dealer for Subaru OEM pads. I was impressed by the affordable of OEM pads so I bought them then and there for the front and rear.

What I like about the OEM pads is they work well without being warmed up and they don’t produce large amounts of dust. I have alloy wheels and hate them dirty. The only negative comment about OEM pads is they fade under extreme conditions but brake fade is a non issue for me as I don’t track the car. After buying the pads I went over to Autobarn and bought a 500ml bottle of Motul 5.1 brake fluid. That should keep my mechanic busy next service.

Best Gear Oils for a Subaru WRX MY08

Gearbox / Centre Differential gear oil

Subaru Extra-S 75W-90 is a highly refined mineral gear oil. The gear oil is manufactured by a subsidiary of Shell in Japan and only sold in 25L drums. Extra-S is not only made to Subaru specs but is the factory full in the gearbox / centre diff and rear diff for the WRX. Whille Extra-S is not sold in Australia, I import it by the litre from U.S.A. The gearbox of the WRX is really fussy so don’t use a fully synthetic gear oil or you will differently get grind. Since this oil isn’t synthetic I would change it more frequently. Extra-S doesn’t like the cold so don’t use it is you live where is snows. I change this gear oil every 25,000 KM.

Rear Differential gear oil

Motul Gear 300 75W-90 is a fully synthetic ester (grade 5) gear oil. This oil works very well in the cold and hot temps. Gear 300 handles the heat really well which is important since the rear diff is small, only taking 0.8L or 1L for Australian models. Gear 300 lowers the noise of the rear diff compared to OEM Extra-S. Since this gear oil is designed for rally / track use I would change it more frequently. I change this gear oil every 25,000 KM. Subaru Extra-S gear oil 75W-90 and Motul Gear 300 gear oil 75w90

Best Engine Oils for a Subaru WRX MY08

Engine oil for Winter

Motul 8100 X-cess 5W-40 is a fully synthetic POE (grade 4) engine oil. I change this oil every 6,500-7,500 KM. Personally I be leave the oil change interval of 12,500 KM for a turbo charged Subaru is far to high. I use an engine oil with a 5W to help with the cold starts in the morning (4*C to 4*C). I’ve had good results with this engine oil and will continue to use it next winter. This fully synthetic engine oil with multiple manufacture approvals performs very well and I highly recommend it. I use an OEM Subaru oil filter.

Engine oil for Summer

Motul 8100 X-max 10W40 is a fully synthetic POE (grade 4) engine oil. I began using X-max to combat my thermal stress causing shearing issue I had when using X-cess during summer. With multi-grade SAE oils, the broader the SAE numbers the more viscosity improver needed. In a engine oil with a very broad multi-grade SAE such as 0W-40 or 5W-50, more viscosity improver is used. Viscosity improver (VI) is often the first component to degrade in fully synthetic oils, well before the base oil degrades. I use a 10W-40 SAE to to help with the hot summer days (28*C to 45*C with an average of 32*C). I change this oil every 8,000-9,000 KM. On paper this oil is very close to the specs of Shell Rotella 5W-40 full synthetic which has been raved about on most U.S Subaru forums but isn’t sold in Australia. I use an OEM Subaru oil filter.

Engine oil for Track Days

Motul 300V Chrono 10W-40 is a fully synthetic ester (grade 5) engine oil. This is a racing oil and should be used as such. I wouldn’t recommend using it for daily use as it lacks the amount of detergents normal engine oils would contain. Before a track day I would dump out the existing oil and fill it with 300V. I change this oil every 5,000 KM. The use of an ester base stock means the oil will be able to withstand high engine temps without shearing. I would recommend using a pink STI oil filter when using this oil. Motul 300V Chrono 10W-40 racing engine oil

Repco has decided to no longer stock Motul oil

A few weeks ago I went into my local Repco store in Albury to find they had moved all the Motul oil from the shelf. I asked a staff member at the enquires counter where the oil was moved to and he informed me that Motul was no longer going to be stocked at Repco and they had moved there existing stock behind the counter.

I went into the store yesterday and to find that all the Motul oils are on the sales table with 10% off. Not exactly a good deal because Repco give customers 10% already by providing a valid NTMA, RACQ or RACV card.

I think that Repco dropping the Motul range is a big blow to car lovers who use this oil like myself. From now on I might be forced into ordering my oil (Motul X-cess 5w40) in 20/25L drums to use in my Subaru WRX 2008.
