thanks！Some good reading for those who want to educate themselves on newer standards in oil and engines
The reason that people say if you do a lot of short trips has nothing to do with the temperature of the oil - it has to do with thermal cycling of the engine causing increased engine wear. More wear causes more contaminants in the oil.I've never heard of changing the oil more often if you only make short commutes. I always assumed the reason why oil broke down was because of heat. Seems shorter commutes in a cooler climate would provide a lot less heat.
If Volvo could have made the oil change interval 15k miles, they would have. The fact is that ALL of the Drive-E engines are turbocharged, and many are turbocharged AND supercharged. Turbo/super charging an engine causes higher oil temperatures, which causes oil to break down faster. Synthetic oil definitely lasts longer than standard dinosaur oil, but that is offset by new engines being harder on oil. The synthetic oil isn't there to get you 10,000+ miles, it's there because it's absolutely required by the severe service of forced induction engines.I will likely be changing my own anywhere between 10-15k miles using synthetic
The filter is on the bottom, so you're down there anyway.So I have a Mityvac fluid evacuator and used to do oil changes on my Land Rover via the top. Basically, the MityVac tube runs down the dipstick tube and sucks all the oil up. I could access my filter from the top, and then re-fill once done. Never had to even get below the car or pop the drain plug.
Given our oil gets checked electronically, does anybody know if we can do this on the XC90?
If I remember correctly, I read it somewhere Volvo (or maybe an individual dealership) will service your Vehicle at 1 to 1.5k miles variation to the 10k, 20k and 30k. So basically 18.5k to 21.5k miles for the 20k miles service and they will service it. You should probably confirm this with your Dealership. It would work nicely in your case if you do a 18.5k service and then a final free one at 29-29.5k.Good discussion here. I am on the 'follow the factory guidelines' path in general. I'd like to get an opinion and I am also going to run this by the dealership. I bought a 2017 S90 T5 Momentum used. The vehicle had 11,300 miles on it when I purchased it. The original owner had the 10K service performed at 7500 miles by a local dealership here in Raleigh, NC. I have a copy of the service order because it was in the dash at purchase. The car now has 17,500 miles on it and the service indicator light is on (as expected). I'd love to get back onto the '10K/20K/30K' schedule so I am thinking about letting this run until 18,500 miles, then adding another 1000 miles at the 28,500 interval (doing the work at 29,500) then getting back onto the normal demarcations at 40K.
Like @stick_shift, I plan on having UOA performed and I also use Blackstone labs for UOA on my 2016 GMC Canyon (Duramax Diesel engine). Not because I feel that I 'have to' but more for my own curiosity! BTW @stick_shift - my Canyon had exactly what they talk about with new vehicles showing up higher than normal metal content due to break in wear. It settled out for oil changes 2 & 3 and now after #4 is pretty low. Interval on the Canyon is calculated via driver info computer (% Oil Life) but in general is 7500 miles or so for the way I drive it.
So - the question here is, "How 'risky' is it, if at all, to slightly extend the service interval (adding another 10% to it)?" I am confident that Volvo has some variability built in, but not sure how much. Plus there is an issue re: extended warranty (I have a 6 year, 100K mile Volvo VIP Platinum Warranty) that requires service 'according to manufacturer recommended intervals'. All this being said, I am pretty comfortable with tacking another 900 - 1000 miles onto the window, but wondering what you guys (and girls?) thoughts may be in this area?
Stick shift, thanks for posting that. Here is mine. Note that the dealer changed the oil as per Volvo at 10k mile intervals. They forgot to get an oil sampling for me the first two times. But here is the third. It's bothersome to me. First, Blackstone measured the oil to be 5W-20. The dealer wrote Castrol Edge 5W-30. It's no biggie, but for once I'd love for dealers to get this right. Secondly, how do I know if they actually changed the oil? Since I have a lift, I will eventually look under there. I am almost certain that there will be screws missing... <sigh>As promised, here is the UOA. It seems to be well worth it to change it out at 5k or even earlier, especially if you're committed to long term ownership. (Those leasing probably don't care...)
I know this is an old post but according to Amsoil website, the correct amount of oil including filter is 5.9 Quarts.I've been putting 6.2 quarts in Drive-E engines since they came out and can tell you that is how much they take.
They may have made a typo.I know this is an old post but according to Amsoil website, the correct amount of oil including filter is 5.9 Quarts.
I realize this is old and the poster clearly just signed up for this one post. But I don't get my specs from aftermarket websites.I know this is an old post but according to Amsoil website, the correct amount of oil including filter is 5.9 Quarts.I've been putting 6.2 quarts in Drive-E engines since they came out and can tell you that is how much they take.
