Mr. Ben, My headlights where not too low. I was surprised how much I liked them and they are far better than any other car I have owned. The cut of line is really sharp and distinct so maybe that gives the appearance they are aimed to low since the HID is so bright. Also the HID headlight are...

I also have a 2016 Mazda 3 S Grand Touring. In regards to this car my recommendation would be to stick with the recommended 0W-20 viscosity oil. Because of medical treatments I have had a lot of free time on my hands the last couple of weeks and have been reading a lot about the Sky Active...

Good points. I really expect the chance of an oil related engine failure to be highly unlikely these days with most engines, especially up to 60k. But one point I was trying to make is for any warranty repair work and especially something like a complete engine replacement it is my understanding...

$70 for a cabin air filer replacement? That is where you can save a bunch of money. If you do not do it yourself next time an independent shop should be able to do that for a lot less. You can probably get a much cheaper oil change with better oil at an independent shop as well. If they are...

I just bought a Mazda 3 with the SkyAcrtiv 2.5 and have also been deliberating between 0w-20 and 5w20. What is driving this that Pennzoil Ultra is really hard to find at a reasonable price but 5w-20 is available at a much lower price. There are also many other fine oils in the 0W-20 range so...

I just bought a 2016 Mazda 3 with the SkyActiv 2.5 engine and saw this 0w-20 oil recommendation for US, Canada, and I believe Puerto Rico, and 5w-30 for everywhere else in North America. My best guess as to why this is I doubt that 0w-20 in readily available in Mexico and Central America but I...

I ordered from Walmart two 5 quart jugs of Pennzoil 5-30 Ultra for $27.97 each with free shipping last month that arrived in about a week. You can have it sent to store for pickup if you want. They are currently out of stock but knowing Walmart if something is selling well online they well be...

The oil flow though those two filters will be the same. Engine oil pumps are almost always fixed displacement pumps and the flow of oil is directly proportional to the engine speed. If one filter has a higher resistance than the other, then the oil pump will simply output a higher pressure to...

Another thing to consider is that it is my understanding than in Japan hardly nobody does their own maintenance on their cars. Most Japanese do not have a garage to do their own oil change in. If fact I believe it might be illegal to do car repair even on your own car unless you are a certified...

I read some years ago about a guy who used copper tubing for an oil line to his turbo charger. The line fatigue cracked and sent oil all over his engine which caught fire and the car burned up. He said he learned after this that copper should never be used in automotive applications because it...

What I found interesting in this article is if I am reading the paper correctly the oil pump on this engine flows as much as the Subaru engine oil pump which is supposed to be one of the highest volumn oil pumps for an automotive engine and the reason for the high oil filter bypass valve...

I am not an oil filter engineer, but I would think that the bypass valve is probably open on most oil filters after a cold engine start until the oil is warmed up to near the normal operating temperature. Engine oil at normal engine operating temperature is less viscous than at ambient...

They apparently are thick enough to do the job. I have only heard of two instances of a oil filter can ruptering. One was on a motorcycle where the filter was struck by a rock, the other was a race car with high single grade racing oil that was cold started in a Montana winter and the engine was...

Yes but the oil change shops were doing a engine oil change and not a transmission fluid change and were removing the transmission filter thinking it was the oil filter.
