uhhhh if you responding to me......should i be using something other then 5w 20?

I think most here agree that 5w-20 doesn't really cut it. 5w-30 or 10w-30 of some decent brand should be the safe bet I guess.

Well I guess i am going to search because there is bound to be a huge thread on this. Is there a brand that the majority of the forum goers swear by?(sry about the thread hijack)

Wow . . . definitely price out the same grade of oil and do it yourself, or even find a reputable local shop to do it.

That's some big brass balls charging you over 100% more than they charged the previous owner. Was that previous price at the same dealership?

Yes, you are missing about 239494300211 threads on oil types, synth v. dino, brands, weights . . . etc. etc. ad nauseum . . .

:)

The dealer, and the oil I bought, use the Mazda Dexelia Ultra 5W30. I plan to do my first oilchange ever soon :Eyecrazy: (as in, by me with my own hands, not the car's first )

Don't you always drive with oil in your trunk anyway?

I see now why the previous owner got charged so much less. He had them buy Castrol Gtx for the car and not the Mazda recommended one. Yeah I've always carried around a 4l of mentioned oil above that I got from previous owner. But it's empty now. I think I'll go for the Dexelida but change it myself to save some money atleast.

Problem solved. As an added bonus - it's always more fun going the DIY route!

if your paying THAT much for it, why not use Shell Helix Ultra?

There's none better.....

S

What's the proof that it's the best?

wtf? that's royal BS right there...
i get my oil change at the dealership here sometimes when i'm too lazy and it's $35.00

Did you import your car from the US? In the US Mazda recommends only 5w20, because of fuel economy goals. If yours is a European model, maybe you have a US oil cap.

The oil chart from an Australian owner's manual was posted here a few months ago. It showed 5w20, 5w30 and 5w40 as being interchangeable over the range of -30 C to + 45 C. 10w... were good down to -25 C, and various upper limits. 20w... were good down to -15 C. Temps above 45 C needed various flavors of ...w50.

Based on that chart, I'd recommend 5w30. My local dealer has started using 5w30 instead of the official 5w20, and Virginia is a little warmer than Norway.

My opinion is that regular oil, not synthetic, is just fine. Others differ. There's general agreement here on frequent oil changes, every 3000 miles.

I know Norway is expensive but I can hardly believe they only charge $35 for oilchange and oil using the Dexelia oil that's worth its price in gold here.

hell it's $25.99 for an oil change around here.

Using what oil...? Or only for the change?

I pay $30 for an oil change at my dealer. That includes the cost of the oil and filter. They use Castrol GTX. Also within that price they look the car over for problems and top off the fluids. I have not had to buy my own windshield washer fluid since I bought the car.

Ken

Most places in the US will be around $30 for oil change w/filter. But that doesn't really help you much, does it? lol

I paid 36 for an oil change here in VA. Usually do my own but the miles were getting high enough it couldn't wait for my spring break (when I go home)

Shouldn't really be surprising to us should it, when I imported my car it was $70,000 after tax and crap with the currency rates at that time (more like 60k with todays rates). Paying 25 bucks for a litre Dexelia oil at the dealer isn't surprising. But yes, getting it cheaper and doing my oil change myself should save some money :)

Heh yeah, I've already accepted that this country is fucked up. I'll probably buy the Dexelia from Mazda this time paying blood price and change it myself. I don't really have much money to spend on buying large suppliements of oil atm.

Most RX-8s are quite reliable, and while most here choose to use thicker oils, the vast majority of RX-8 owners in the US, I assure you, are using 5W-20.
Are you missing something? Hardly. That said, I'd follow Mazda's reco for the country you live in.

Isn't AGIP quite popular over in Europe?

WTF? Conventional Castrol 5w-30 will work just fine.

Silkolene Pro-RR 0w-30 is my choice of the amber nectar, don't have any oil pressure or temperature trouble or fluctuations, even with the abuse it gets.
About ~240USD for 8 litres though.

well .. i live in karachi pakistan ... i own a mazda rx8 6 speed 2006 .. am using redline 10w30 since 2 yrs .. and i change it every 3000 kms .. working fine ;)
