Hey all. Just wanted a quick opinion. I've always been a fan of full synthetic oils and I don't mind paying the higher price. I've only had one oil cha he since owning my Volvo since January, and I just had Volvo put their oil they have in. I want to get 7.3 quarts of Mobil one and have them use that.. Do you think this is okay to do? My car has almost 200k on it and I was gonna get Mobil 1 high mileage 10w-30 since its summer time right around d the corner. Thanks for reading!

 

Yeah just being your own oil in and tell them that's what you want in the car. I have customer supplying all of the time when they get their oil changed

 

Okay, thanks. I just always heard the myth of switching from conventional to synthetic and different detergents and swelling of seals and all sorts of stuff. I want to start using quality oil since the mileage is getting up there.

 

well i changed to synthetic oil on my Lexus after 100K and so far my car has almost 200K and no problems infact iwould think its actually helping the engine. Now volvos have different engine and turbos and stuff but i would still think switching and sticking with synthetics would be best choice for your engine and offcourse OEM filter too..
i also do use mobil1 too and its the best of other synthetics i have tried.

 

You could switch over to synthetic in 2 stages if it makes you feel more secure about the decision to change over.
Use a quality semi synthetic, the first change and then follow that up on the following service with your full synthetic oil if all looks good.
New filters of course at every change.

 

I prefer the extended life Mobil 1 based on my experience of running it, vs regular Mobil 1. I had noisy lifters at startup at 3k in my 2007 GMC pickup using regular Mobil 1. With extended life, this didnt happen before I changed the oil at 6k - which was all highway miles. I credit this to the extra "zinc" in the extended life Mobil 1. This is noted on a chart they have produced for all their oils.

That said, I also tried Castrol Syntech full synthetic and never had the noisy lifer problem, so I have stuck with it now in all my vehicles.

Still, I think Mobil 1 extended life is probably equal in protection. And they have some great programs for discounts if you sign up online for rebates, etc... You can do that here: Mobil 1™ Synthetic Oil | Official US Site
