Recommended Oil Type

36 posts in this topic

i'm getting an oil change soon and was wondering what oil brand and type you guys use? what oil brand do you guys use with your mazda and recommend to me?

my odometer reads 165,000 but i have a new engine in the car from a 98 mazda 626 that was wrecked.......so my engine really has about 80,000

thanx for any input given on this topic.

Pretty much it depends on your own personal preference. Some on here run Mobil 1 synthethic, other on here (like myself) don't think it's worth the money on a stock motor with such low performance. You can really run any brand you like, provided that the viscosity is correct for your area. Check your owners manual to find the right viscosity.

If you've never heard of it, Bob's Site has just about everything you've ever wanted to know about motor oil on there. Read up on that a bit if you don't already have a favorite oil, and go from there. B)

I use Mobil1 5W30 because I do extended OCI. But any dino (10w30 summer or 5w30 in winter) will do if you change it every 5k miles based on Owner's Manual under severe service.

For the first 60K miles, I used Valvoline 5W20 dino and changed it every 5K miles. Now that I've hit 60K+ miles, I'm using Valvoline 10W30 dino and changing it every 3K miles. However, I'm debating on switching over to Mobil1 10W30 synthetic along with AMSOIL synthetic tranny fluid. If I did the synthetic switcheroo, I'd push my oil change intervals out to 7.5K-10K miles.

Owner's Manual Recommends 5w30 or 10w30 because of winter. But if it's summer, you can use straight 30 weight.

If you are using synthetic, you can use 5w30 the throughout the year regardless of weather because it is synthetic and it stays 5w30 all the time! B)

If you are using dino, use 10w30 in summer, it contains less additive to achieve 10w30 (20 difference) compared to 5w30 (25 difference). Meaning less additive breakdown. The lower the additive, the better the oil. Stick with OEM filter.

I WORK AT AN LUBE CENTER AND WE GET THIS QUESTION ALL THE TIME. AND

TO BE HONEST ITS ALL REALLY PERSONAL PREFERENCE WHEN IT COMES TO BRAND! OIL IS OIL

AS LONG AS YOU ARENT USING SOME WALMART/KENDALL BRAND IT DONT MATTER.IT DOES THE SAME THING. AND AS FAR AS VICOSITY,CHECK YOUR MANUAL.ITS ALL BROKE DOWN. AND ITS NOT REALLY GOOD TO RUN SYNTHETIC IN HIGHER MILE ENGINES.TO MANY ADDITIVES.I WONT HURT BUT IT WONT HELP EITHER.RUN SOME KIND OF HIGH MILEAGE OIL FOR ENGINES OVER 75,000!

Synthetic has less additive. Why, because it doesn't need to protect tha base oil. Base oil doesn't brake down.

Oil that has a big difference in multigrade value has more additive. 0W30 (30 difference) has higher additive than 10w30 (20 difference) and 0w40 has the highest difference, highest additive content. To try to maintain the grade as well as try to keep the base oil from breaking down, conventional oil use a lot more additive.

If you can live in a warm country (always 35F) and your car specifies 10w30 or 5w30 in winter, use straight 30 grade synthetic oil and you might never have to change your oil ever! B)

About the oil factor I hear that mobil 1 is not good for mazda engines, something about it containing sulfur and it not being good for mazda engines, but as far as I'm concerned I know people that have ran over 150,000 mile on their 626 with mobil 1 and no problems. So I don't know.... B) I say go for Mobil 1. I also hear that castrol GTX for higher mileage engines is great, but never seen it used in a 626.

This is for the rotary engine only.

I used 15w-50 becouse i thought it would become hotter, but still cold.

I used M1 110 filter to back up oil's millege. It is still clear and about 3k i went on that oil.

vanilla sky; if your car doesn't leak oil, then go synthetic.

That is exactly wrong! If u have 171,000 miles on a car all the seals are old and are form fitted to that engine. Since synthetic oil is thinner than conventional oil it will find every leak available. SO if its a newer engine u can chance it but if its old stay with the good old petroleum...whats the harm ur engine was fine before just make sure u change the oil regularly!

no, synthetic is NOT any thinner, it just doesn't change viscosity like petro based oil... thermal breakdown is something i don't have to worry about...

and by the way, i know of one of those motors (the one i referred to that has 171,000 on it) that had 250,000 miles on it and when it was torn down looked brand new inside. it had absolutely NO compression loss and not a single sign of burnt oil... of course, this car saw synthetic since day one (recently accuired 1 owner car, records were present)... can't say that about petroleum based oils...

PRO-LONG

Just read this..And I promise you that I have seen that it`s actually works.

USE PRO-LONG AND MOBILE 1 OIL TOGETHER, AND YOU HAVE ONE OF THE BEST OIL, EVER:)

Good luck

I don't believe in this whole additive market. I don't think anything is better than Mobil1 alone.

addictives will mess up the oil. just run mobil 1 syn and evrything will be okey. you can add adictives when flushing the engine stuff.

several consumer products watchdog companies have tested pro-long and additives that make claims like pro-long... turns out that it's not much different than baby oil (yeah maing, some redline and some J&J y0)... if you read the warrantee paperwork that came with your car, you'll see that additives like that will void your warrantee because of ill effects that these products sometimes bring on... i tend to just stay away from any and all additives...
