While my drive is a little longer than yours, 10 miles one way, it won't hurt it. Here we can go from -20F to 100F+ with high humidity, I ran a full year, about 5,600 miles of absolutely nothing but short trips, on M1 EP. my UOA is over in the UOA section. Everything came back perfect except for a little bit of fuel dilution, but I did take the sample cold.

As for not doing them more often... the oil is good for that long or longer, why waste it?

You keep mentioning typical US brands, what other brands are available locally?

nothing is cheap here in-fact its all extremely expensive,parts can be twice to ten times more than the states,cars are 2.2 more than the states.
one quart of m1 is16.5 $.
i said cheap relativly to other maintenance or car problems.
we have all the major brands like m1,castrol,valvoline,ex, pp only comes in 0-20w and i need 5-30.
 
its insane gas is 4 times,food is 5times,its mainly due to security needs and also because its a very fast growing country.we work the most hours,get paid the least and pay the most in the western world.
but its all good.

i get the m1 and the m1 ep at the same price,read somewhere that changing oil to often is actually bad is it true? and if so what is to soon?


Go with the Mobil 1 EP. Changing it too often won't hurt a thing.

Will M1 EP prove to protect better during a 6 month 6 km oil change period?

Maybe, maybe not. If it can be bought for the same price why not use it? The added benefit would be if the OCI has to be stretched, EP would provide a little safety margin, if needed.
 
i cant go over 6 months without changing oil its stornger then me,if i last 6 months im on my way to sanity.ðŸ‘
on my cts i lasted 4 months and that was with redline.thats my personal not changing oil best.

Here are some general guidelines for engines in good condition and driven in "normal service" :
Regular Mobil 1 goes up to 10,000 miles and Mobil 1 EP goes up to 15,000 miles.
These guidelines are adjusted depending on your driving habits, ambient conditions, and engine condition.
The ONLY way I would go more than 15,000 miles on an oil change is with a large oil capacity sump and the driving is mostly highway.
Hope this helps you.
 
I once did the same but after further research learned the three to six month recommendation was based on older natural petroleum products that had undesirable compounds like paraffin's and aromatic hydrocarbons. The major makers synthetics are really really good these days compared to oil even 20 years ago. If fuel dilution isn't an issue and you have a normally aspirated port injected engine (not one of these nifty new GDI turbo's forming those soot/carbon scrubby pads in your engine) a once a year or 5,000 miles (whatever comes first) OCI would be a cakewalk for any Redline or Mobil1 product (or any of the other major makers synthetics).

The OP mentioned a Mazda SkyActiv engine, which I believe is GDI.
 
Good catch Y_P_W I missed that, yes the Mazda skyactiv engines are all direct injected and the N/A ones run 13:1 compression so depending on driving style can have some fuel dilution issues as well. Yep six month intervals would probably be safer for that one.

I was thinking for a fuel diluter where the manufacturer doesn't specify something more expensive like 0W-20 or even "synthetic 5W-30" like Subaru does for its turbos, then an inexpensive oil changed frequently would seem to be a good choice.

Mazda seems to spec any API GF-5 5W-30 as suitable. If it were my car in the US, I'd probably just go with Chevron Supreme 5W-30 (especially SN Plus if I can find it) and change it twice a year or mileage based like the OP is thinking of doing.
 
i will go with m1 ep twice a year,the manual suggests every 6 months or 6k miles which ever comes first in severe use.
on that note whats the equivalent to m1 or m1 ep with castrol or valvoline?im looking for strong film,low noack and cleaning power.basically for the best out of thos three companies yes i know its an apple and oranges question but hope to get real facts for what is best if there is one over the other.
i like m1 for some reason.
tnx

Seems kind of excessive. I'd certainly understand if you had some sort of exotic car or a turbo and you just want that little extra bit of protection. However, going with M1 EP and then dumping it at severe service intervals just seems like you're pouring money into the drain pan.

Do you have an oil life monitor? At least around here the new Mazda engines have that. If you're using something like M1 EP I wouldn't really worry about going through the full OCI.

Short trips are one thing. I believe the biggest issue is fuel dilution in a cold engine. But that's also a big issue in

However, 6 months is considered a pretty short oil change interval these days. If you're changing a "conventional" oil often then you. The big thing about a "synthetic" (which is really a marketing term more than anything else these days) is that they generally should last longer. There's not necessarily any benefit if your cooling system is working and you're changing it often.

At least in the United States we're paying relatively low prices for our motor oil. That 5 quart container of Mobil 1 EP is about $30 at Walmart, and that's actually kind of expensive. At that price some people even use that for short intervals. But where you are I'd look at the prices.

There have been a lot of cars on the road that have engines last a long time on just "conventional" oil changed at the manufacturer's "severe" oil change interval. If you really want to I don't see why it would hurt, but I'm not sure you're getting any benefit from Mobil 1 EP. Frankly - I'd probably use Mobil Super (conventional) for any car that specifies just the basic API gasoline standard. I've used that in my parents vehicles where I'll change the oil for them, and for my wife's car. I've used the equivalent (different name at the time) back when I first had my WRX on the advice that "conventional oil" should be used for a few thousand miles for engine break-in. However, since it's a turbo I've fed it a steady diet of Mobil 1 (5W-30 or 0W-40) over the years even though I'd sometimes go beyond the manufacturer's recommended "normal" interval.

tnx


Research I read states synthetic do a little better than conventional.

Synblends are not universal. There's too much guessing-game there. One synblend may be 15% - the next 30%. I don't know of any above 33% synthetic. The best synblends are your own blends (my opinion). Mine usually are a 50-50% compromise and I have 2 full synthetic blends going on right now, see my signature.
