What Oil Do You Use?

I've always been stuck on Castrol Syntec. I've wanted to do the switch to full Motul but it's quite expensive

Castrol is one brand I noticed to be popular with a lot of Honda enthusiasts and even just regular folks buying oil. Anyone here set on going right to the dealer? Some people feel inclined to get "dealer oil"

Amsoil Signature Series and matching filter, only the best.......

Thinking about Penzoil platinum 0w20w. Any thoughts? I have never used it before.

Not sure if Walmart reviews are a good judge for Penzoil platinum 0w20w but the reviews are positive. Amsoil is a better pure oil IMO but it's not the cheapest out there.

Depending on which dealer you go to, the dealer oil is typically you're regular brand because they buy in bulk. Chryslers all about Mobil 1 when you want full synthetic , but it's usually just whatever the local dealer can attain from the local suppliers for a good price.

The best built 0w20 IMO is Red Line's formula, I'd love to run it but since it is not API certified Honda could void my warranty and I have an extended warranty that I'd like to keep in place. I will have Honda do my oil changes but I may supply the oil to the dealer.


Hanging out at bobistheoilguy.com the Pennzoil sponsors are offering me enough oil for two full oil changes, plus used oil analysis testing kits , all for free, and they are supply Pennzoil Ultra which is their top notch synthetic oil. I'm going to run it on two oil change intervals after the factory fill is drained, depending on the test results I may keep running the Pennz. Ultra. My other choice would be Amsoil Signature Series 0w-20. All great oils.

Always with "Liqui Moly" "Simply the Best oil"

I know its pricey but this German made oil never let me down~!!!

It's a shame that their oil contains zero moly, despite the name, lol. My preferred additive in motor oil is Moly, but oddly enough Liqui Moly doesn't use it. Our factory fill oil comes with boatloads of Moly, Red Line and Motul use copious amounts of Moly much like our factory fill levels, some other brands use it at lesser levels, too bad Liqui Moly doesn't have any in their formula or I'd consider it. I'm sure it is a good oil though.

That's just false advertisement in the name itself...Is Simply the Best oil SPI certified and has anyone tried it?

Darn it~ I've been fool for last 5years???

anyhow....I've noticed more smooth, silky drive and less engine noise with liqui moly...
oh~ and also getting more mileage(about 2miles) with my old 2005 highlander.......since than I'm stick with liqui moly and happy ^^

I've only used full syn Mobil1 in all of my cars since 1993. Never ever had any engine problems, despite stretching change intervals out longer than they should have been.

I get 5 qt jugs at Walmart for about 25 bucks. Throw in a decent oil filter for 6 bucks, and every oil change is not much more than 30 bucks. Do I like doing it myself? No. Jacking up the car and cleaning up afterwards is a PITA, but I've never paid anyone to do an oil change, probably won't start now. I don't even know how much a full synthetic oil change costs.

Stick with what you like and what works for you. It can still be a great oil but I just found it odd that the name and formula don't necessarily match. I believe they only weight they add moly to is 10w40 for some odd reason. There are many great oils without moly but I prefer it if at all possible.

Mobil1 is a great oil, they have come up with some great formulas over the years. For some odd reason they get a bad wrap on the internet and particularly with Honda owners for some reason. But they are one of the few manufacturers to pass the extreme RDX specification for Honda a few years back HTO-06, and got Honda's endorsement for that turbo motor in 5w30 viscosity, and the vehicles rolled off the assembly line with Mobil1 oils.

Ah the missing moly is being added by this MOS2 additive. It can't hurt if used in the appropriate concentration, check the recommended mix level as our sumps are kind of small. It is TUV approved so it is supposed to work as advertised. Don't go overboard with additives, if you add a few more cups of sugar to a cake recipe it doesn't necessary taste better, same thing with additives. Moly is a good additive to provide extra protection when boundary layer film strength is broken down and you get metal to metal contact. It may also leave a bit more wear protection between starts. At worst it may do nothing, at best it may help a bit in some instances.

Pennzoil is shipping me a 2 year supply of Pennzoil Ultra 0w-20 for free, all I have to do is send in sample used oil analysis after each run, and they pay for all of the oil, shipping, and used oil analysis kits. I couldn't resist the offer. They contacted me through bobistheoilguy.com and they are eager to test out our motors with their top notch synthetic oil.

Reference link for those that don't know what this "Moly" is : https://bobistheoilguy.com/moly-basics/

I'll find a list of oils that Ive seen that breaks down moly levels.I believe Redline has some of the highest levels in their 0w/20 synthetic line.
