I'm considering replacing my '98 S70 with an '06 S60, and one of the advantages is a longer interval between oil changes. I run Pennzoil Platinum in my S70 and am wondering if that would be OK in the S60 with the higher interval.

 

Honestly, ignore the interval and just change oil as often as you are accustomed to doing.. its a nice insurance policy and wont really cost you THAT much more in the long run

That said, I use Mobil 1 10w-30 change every 5000 miles

 

+1. Don't change your routine on account of what a manual says.

I usually run PP or Castrol Syntec. I change my oil every 3 or 4 months, regardless of mileage.

 

+1 on Mobil 1

I try to stick to 5,000 mile intervals.

 

Pennzoil Full Synthetic

 

Mobil 1 10-30w in the S60 and Mobil 1 High Mileage 10-30w in the V70...........I used to go 5k or 5 months but my new Volvo mechanic recommends doing 4k/4months and that's the interval I'm switching to. On my Benz, I do 5k/5 months but it also has an eight quart oil capacity v. the six quarts on the Volvos.

 

Castrol Synthetic 5w30 for the Florida heat!

 

Per my wife's '06 warranty & maintenance manual, there are a variety of viscosities recommended, but 5W-30 is the "all purpose". Depends, of course, on climate, and towing. Volvo says 7500 miles without differentiation for type of use; but I tend to think that's optimistic. For some reason, the manual and the filler cap both say "Volvo recommends Castrol". And, it adds that syn is recommended for vehicles used to tow.

If you have a turbo, I'd think synthetic is a good insurance policy since it resists "cooking" better than non-synthetic. The oil in the turbo bearing gets plenty hot. And as anybody old enough to remember 1980's Chrysler turbos can tell you, coking of the oil is not a pleasant thing to deal with.

 

Somethng, im surprised you use 5w-30 in florida.. .as far as I knew, 10w is what you would need to withstand that kind of heat properly...
I just use the m1 10w-30 to play it safe is all

the bottom line is, Synthetic > Dino Oil

 

Recomendation of 2 Stealerships.

 

Amsoil 5w30 and I change the oil and filter according to the maintenance schedule.

 

Stick to the factory recomendations on change intervals. They didn't make those numbers up just all ***** nilly.

My experience with oil. And I have torn apart a few motors thats I've built. Its basically all the same. Sythetic is less likely to coke up and or cook off, so therefore it lasts a little longer. BUt other than that its the same as natural oil. There is only one type of oil out there with a vast difference to other oils. Oil for diesel vehicles. Because they are allowed to have a little bit of zinc and some other stuff in their oil that oils for gasoline engines can't have. that being said. I run Rotella Super T, because. It fights against sludge, it has less ash in it, it operates better at higher temperatures, its way less likely to cook or coke, and finally its made for vehicles that don't stop running for sometimes days on end. I put it in my 242TI and I rape that thing no matter what the temperature is.

 

I run Amsoil full synthetic in both my Volvo vehicles. I follow Volvo Canada's reccomendation for synthetic and change every 12,000kms. My '06 just turned 200,000 kms totally trouble free, just regular scheduled maintenance.
Cheers!

 

Castrol Syntec 10W 30 on all my cars and by owners manual every 7500 miles . Not sure but I think 5w30 is for cold weather not for hot. I live in Arizona

 

You're right. Those "low" first numbers are for cold weather starting mostly, but also help boost EPA fuel economy numbers which is why we don't all run 10W40 any more. Lower
viscosity # = thinner oil which runs better at lower temps.

 

interesting article all about oil
