I'm in the east coast, no 93 or 94, only 91 and no Chevron... I thought Esso was still Top Tier, I've look it over and a lot of gas stations are not in the Top Tier program anymore, what happened? I agree about the oil changes. Of the 16 000 km oil change, I expect about only about 5000 km of...

The premium fuel here used to be ethanol free but I doubt it is anymore... That would have reassured me a bit. Also not a fan of putting additives in a brand new car, that's why I wanted input. Thanks!

Hi BITOG, Been a while since I posted here, missed you guys. So, I just traded in my Forester for a Rav4 Prime, very happy about the switch. Being a PHEV, I can realistically go on months on a full gas tank, already going weeks without have the ICE starting. My concern is fuel related, since...

That's the best oil I've used in my FA20DIT. I also got confirmation from Shell that it is SN plus certified which should help for LSPI.

40k km later and I'm still using the RTMV, wonderful oil. It quiets my engine so much. I hope they will keep making it for a while.

I have tried many oils in my FA20DIT (FA24's smaller brother) and ALL of the GF5 oils I have tried has sheared down a grade. Then I tried higher HTHS oils like Rotella Multi Vehicle 5w-30 and Mobil 1 ESP 5w-30 and they both stayed in grade while having less wear materials in the UOA. In my...

It will be in a garage, so I guess, -10c is the coldest start it will see.

I am in Canada where it gets down to -20 celsius often, does it mean I should get 0w-30? If so, is there such an oil with JASO MA?

Hello, I am about to buy a 2007 Honda Rincon and would like to know what oil to use. It need JASO MA and I am wondering it I can use Rotella MV 5w-30 which is JASO DH2. I do not know these standards much. Thanks!

Sorry for reviving this somewhat old thread, but I have a 2015 Forester XT with the same engine and also used QSUD for a couple of oil changes with the same result. It even sheared down after only 2500 km... Actually, every GF5 oil I used in the past sheared down to a 20 grade. The best oils I...

Originally Posted by Triple_Se7en I never had a vehicle (since 1969) that didn't seem to run better, when switching from 87 to 93 octane. If your car isn't tuned to take advantage of a higher anti knock index it will not change how the car runs in any way. Higher octane does not produce more...
