    Mobil 1 AFE vs Super Synth 0w20

    Hi guys, 0w20s are still hard to come by here but I'm looking at using one of these 2 in my '11 Lexus IS350. The OCI would be ~10000 miles. I noticed the S/S does not have Dexos 1 approval (whether they didn't submit for formal testing or it actually doesn't meet it is debatable) and the only...

    M1 Gear Oil not as good anymore?

    I recently flushed out the TC & rear diff in my Evo X with Mobil 1 Synthetic Gear Lubricant LS 75W-90 and I couldn't help but notice some of its stats aren't that impressive: Pour Point, ºC (ASTM D97) -39 Flash Point, ºC (ASTM D92) 150 Its much worse than their own M1 Delvac 75w90 and many...

    Silicates in a Japanese car.....

    How damaging would it be to use a low silicate HOAT in a Japanese car? Will there be any risk with silicate prematurely wearing out the water pumps that the Japanese car makers fear so much? So my partner and I both have 05 Mazda 3s, (pre 'FL22', Mazda's 2nd generation P-HOAT). Unfortunately...

    Frothy Redline Shockproof with Pics.

    Got my gearbox rebuilt by a shady shop and I decided to drain the fluid which happened to be Redline Shockproof. What amazed me was the amount of air bubbles in the oil - and this car has been sitting for 2 weeks. The oil is so thick that even the surface bubbles fail to break & all the lil dots...

    Synthetic choices for my RX8

    Hi guys, I'm a owner of an new Rx8 and shes done about 2000 miles and I'm ready to change her over to a synthetic. I'm undecided on which synth I should uses mainly because as you would know, the rotary injects some of the oil into the engine to lubricate the seals so a cleaner burning oil...

    Fuchs GT1 0W20 is in!

    So I changed out the Delvac 1 to try out this interesting Fuchs GT1 0W20. On initial observations the motor is about the same smoothness and noise. I've noticed that the idle MAF voltage has dropped a consistant 20mV compared to before, indicating there is less effort to keep the engine at...

    HDEO vs Redline/300V/Amsoil

    So I've been thinking about what oil to run next in my 400hp SR20DET (2.0L 4cyl). Been using Motul 300V and I am always on the prowl for an oil that provides the best antiwear and cleanliness performance as this motor pretty modified (uses a non roller valvetrain too). Here's the price breakdown...

    Motorcycle Oil Comparo

    I'm not sure if this has been posted before but here is a nice ASTM shootout of motorcyle oils. Whilst its not car oils, it still provides good insight into how oils compare! http://www.amsoil.com/lit/g2156.pdf

    Paper on oil degredation

    Found this interesting paper regarding oil degredation in the ring packs of motors; http://www.york.ac.uk/res/gkg/ms/conf_paper_final.doc Well judging by that paper, I'm glad I use synthetic oils as the rate of oxidation would slower! Also it is interesting that increasing the flow rate in the...

    Is this what Amsoil is all about?

    When I heard Amsoil released their new Ea air/oil filter range 4 months ago I jumped right on the opportunity. Being Down Under, there aren't a lot of dealers here but managed to track one down in Adelaide (300 miles away), a city which I visit once every 3-4 weeks. When I spoke to the dealer...

    Transmission life. How to get the best?

    I guess we all can acknowledge the fact that an engine would easily outlast the transmission in most cars. So you'd think we'd be more worried about extending the life of our trannys than our motors? So what could we do to keep our trannies from wearing out besides regular fluid changes? Do...

    Cold starts and low viscosity

    Hey guys. As I understand, a thinner oil at startup means more lubrication. This because when you start up your car, the pressure relief valve is bypassing some of the oil. So for a thinner oil, there is more volumetric flow at the same oil pressure? (Whilst the bypass is active). Eg at...

    Found this after a service from BMW.. Very upset..

    I got my old's 02 BMW 530i Sport comprehensively serviced last week from the stealership (coolant/plugs/oil/all filters etc). Today on the way home I took my olds car for a drive and I noticed the valvetrain was very loud and unusual. So out of my BITOG curiousity I pulled the filler cap and...

    Thicker viscocity?

    I just noticed on my room mates car that the oil was pretty thick on the dipstick. Hes done approx 11,000km of easy city driving on Shell Helix Ultra (XHVI type) 5W40. Its due for an oil change so out of interest I then dipped the dipstick into a fresh bottle of this oil and it flowed down the...

    What Viscosity Really Matters?

    I think this is why we use the HTHS rating? To see roughly the viscocity of the oil in bearing conditions?

    Coolant level in radiator!

    Hi, Quick question! Everytime I check the coolant level in my radiator (not the overfill reservoir) when the engine is cold, there is barely enough coolant covering the core. If I fill it up again, heat cycle the engine, it dissappears again, presumably into the overflow tank. My understanding...
