The wife's Subaru crosstrek is due for it's first oil change. I have never used synthetic oil before. Is any one brand of synthetic oil better than the other for small 4 cylinders? What about the oil filter for this oil? Thanks.

Mobil 1 is pretty good so is pennzoil ultra platinum. I run the napa platinum filters after the factory warranty runs out.

I'm a firm believer in synthetic oil. I mowed the whole yard with a mower that had no oil in it after I drained the synthetic out of it and forgot about it.
NAPA synthetic has worked well for me for 25 yrs. No need to waste money on the expensive stuff.

I use Mobil 1 on all my stuff. Worst case scenario, you can just change your filter and top off the oil, but wouldn't do that very often.

They're all good. Project Farm on YouTube has a video that he tests a bunch. Watch it. Good stuff.

If it’s under warranty use what Subaru recommends. That will likely be a OEM filter they might have their own branded oil.

Synthetic is good stuff! I bought a new corvette in 01' and if you put regular oil in it it would void the warranty! It came with a video showing the differences and it made a lot of sense. It recommended mobil 1 I put it in everything I own including my small engines and my inboard jet boat with never an issue. I highly recommend it!

I'm a firm believer in synthetic oil. Run it in everything from my 3 pickups to mower, weed eater, buggy. Anything with an internal combustion engine.

Bob is the oil guy website has everything youll ever want to know about oil....and probably more. Good info from guys that do a lot of research on oil and apparently dont have enough fun hobbies ...

Mobil 1 should be fine.

Can't go wrong with Mobil 1, Pennzoil, Castrol. As long as it has this cert on it.

I had a friend, helicoter mechanic that was also in charge of the company vehicles as well. You are required to have oil in helicopters analyzed, so on companies dime, he used different motor oils in trucks and had oils analyzed too. Mobil 1 had best ratings.

Any problems using it on older vehicles with original seals?? How about 4 stroke boat engines??

Make sure to use the correct viscosity. Probably shown on the oil fill cap.

I use Mobil 1 in our 4 vehicles . I pick it up at Wal-Mart. It is cheap anymore. Extends your oil change interval too. Honda Odyssey van bought new in 11. 345K, change oil and filter every 10K, no oil use.

Walmart Supertech synthetic is as good as any expensive name brand oil along with their oil filters.

I know that synthetic stuff is really good. I use it in my Tundra and my Sienna. I do have to wonder how much more life I could get from my Tacoma engine with it. I have been using conventional 10-30 ever since I got it back in 2004 when it had 100,000 miles on it. It now has 683,000+ on it, and the only things that has been done to the engine is valve cover gasket replacement and a rear main seal. The bugger does use a quart every 2,000 miles now, but I don't think that's terrible. Again, how much more life would I expect from this engine with synthetic oil?

My dad has been a mechanic for 40 years, all he will use is mobile1 synthetic

Thanks everyone.
