Watched an awesome video the other day on how Mazda is supposedly fixing to revolutionize the combustion engine technology. They are even going to use this technology in a new rotary engine also...... Essentially they run a super lean mixture that is so lean that it will not self ignite...

Man........ lately I have been watching some pretty gnarly videos lately on YouTube having to do with graphene superconductors being built and refined overseas. Supposedly it's also 100x stronger than steel. Also watched a good show about how hydrogen battery systems paired with graphene super...

The ol tundra has a check engine light on...... it's the downstream oxygen sensors saying that poor catalytic converter efficiency/below threshold. I replaced the oxygen sensors a few months ago but had a feeling it was gonna be the cats. My question is that rather than spending $1000 on factory...

Based on VOA and UOAs, who makes the heaviest duty 30 WT? Can be synthetic, conventional or blend.......... Just curious...... Can be diesel or gas rated. ***PS*** I remember a year or so ago watching on a wear test, old recipe valvoline durablend spanking up on all the high dollar synthetics

Has there been any significant proven gains by adding bypass filtration to a gas engine like a 2019 Toyota tundra or the new 6.2 Chevy Silverado DI engine? My current tundra has 264k miles on it and doesnt burn a drop of oil between changes. I love the truck but she is starting to show her age...

I was reading on the Schaeffers synthetic HDEO and I see that IT'S NOT ck-4 rated...... is that on purpose? What's the advantage to the newer CK-4 backwards compatible oils? Does Schaeffer have a special additive pack that makes this 9000 series oil better as just a CJ-4 oil?

Is it typical for moderators to delete threads on this forum and not send any personal messages as to why? I asked about the "high volume 25 year pro" thread and where it went..... it was a interesting thread to say the least.....

Where did it go?

Researching the Kubota SUPER UDT2 blended by Valvoline and looking at customer testimonials, this seems to be the best of the best in tractor fluids? Or is it? I know several people who have switched even their commercial zero turn hydros to this stuff and say the hydro wine completely went away...

Hello all. Just wanted to share the fix to a common issue that comes with new carbuteted equipment. My Honda eu2000i since day one has had a little "hiccup" here and there every few seconds when ran on economy mode which idles the generator at the lowest speed necessary when inverter loads are...

2004 Toyota tundra, aisin tranny Looking for the highest regarded type 4 tranny fluid..... fixing to do a pan drop, clean and filter screen change. Have been using valvoline type 4 from O'Reilly. Fluid still looks good but it's got about 80k on this change....... it's time and Toyota is higher...

I see that the 5w-30 is sn/sm rated and the 5w-40 is not. Can someone please inform me of why this is? I believe I remember readying a while back about CAFE standards or something to the effect of fuel efficiency that a 40wt doesnt fall under. I can tell you this........ after switching my...

Was wandering if there was any benefit to using this parker ht-1000 in my commercial exmark zero turns? Here are some threads going on........ someone mentioned to ask over here...... I'm currently running motul 300v 15w-50 in them I DO operate a small repair shop and if this fluid is good as...

As previously discussed lightly in this thread.... https://www.bobistheoilguy.com/foru...turn-parker-transmission-oil#Post4940098 Does anyone have any information or thoughts of what kind of fairy dust that a oil can make this hydro oil so special? It literally doubles any previous commercial...

Hello all! Got another question for yall professionals..... I have two exmark mowers that I take really good care of and use commercially for a small side operation. I recently repaired one of these transmission on a kubota ZTR for a customer that was leaking and he wanted this "special fluid"...

Scored a major good deal on some mobil delvac 1 5w40. $27 a gallon plus the $13 mail in rebate, $14 for a top quality oil is a win in my book. Anyways on the website it says that it can be used in mixed fleet gas vehicles. Since I use this vehicle all the time pulling stuff and basically driving...

Is there really a difference? Do you really have to put dexos rated oil in a 2015 Tahoe? Why not the delvac hdeo? Does the extended performance 15k mile OCI oil work better for gas engines over delvac 1 esp which diesels run 30k miles ++? I understand they are "just looking out for us" but...

Hi all, I was wandering if there would be any harm in me switching oils in my cookoff machine? Its a Cummins ISL-11 500HP 1550TQ engine with allison 4000mh tranny. Generator is a Cummins onan that actually has an isuzu 1500 cc na engine. It's been on regular tractor diesel oil all its life and...

So all of our vehicles run on the same oil, m1 0w30 afe. . My wife is alot easier on her 2016 Tahoe than I am on my tundra. She has 3k miles on this oil change it's at 56% according to the dash. That didnt sound right so I checked it, it is pretty dang black! My tundra has 9k mules on its oil...
