Engine oil RAVENOL or IDEMITSU

Idemitsu is responsible for the oil that powered the Mazda 787b; they know the rotary like no other. I exclusively use their synthetic 20w50 and premix.

Regarding brands, if you want to stick with factory oil without dealer price, Idemitsu is the brand to get. I emailed Mazda corporate and they said Idemitsu is the OEM for their oil.

i personally use ravenol now, but was a motul and shell user before.

Ravenol based on review videos on FB. Tumahimik makina & the tone ng engine nagiba mas smoother again based on videos lang sa FB not actual experience.

When it comes to oil, Ravenol is really good and is also Made in Germany, some even recommend it over VW or BorgWarner, as it is full synthetic and does not break down/sludge up as fast.

I have used Ravenol USVO DXG 5 - 30. Comes back in most of the testing I see done as excellent oil. I only drive 5k miles year here in Minnesota taking the car off the road by October 1st and not back until at least April 1st, sometimes the 15th, and once in a great while as late as May 1 based on the weather. I change the oil once a year prior to putting it away for the winter. The oil comes after 5,000 mlles out almost the same honey color it went in as.

Ravenol user here (previously motul and shell user). So far, engine temp is 1 line lower, quieter engine, and very slightly better fuel economy. Ravenol for the Altis 2.0, yaris, and rav4.

On 2006 F800S i have used Ravenol. I tried Shell, BMW oil(Shell, basically) and Ravenol. With Ravenol- no false neutrals. At stops i was able to find neutral almost instantly... And engine sounds somewhat "greasy"

The oil i have run: VW brand, Castrol and Ravenol all 0w-20 that meets 508/509. Basically on cooler outside temperatures the oil does run slightly higher than on hotter days.

after 2000km of running on it, i see there is quite a drop (30% from the max point). i think that is very weird...
