Mixing PYB and PP or PU

[HK_Ace]

Vehicle in question- 2006 NA Subaru Forester 4 Cyl with 90,000 miles.

Have been using German Castrol and have run out. So in desperation, I put Mobil 1 HM 5W30 in this time. I don't particularly want to continue with M1 HM and be stuck with it or with a HM oil. The M1 HM is good stuff but may be a bit thick for CO winters and I don't think I need seal swelling. Syn does a good job of keeping seals in good shape. My Subie does not leak or consume oil at this point.

I change my oil every 7,500 but can switch to 5,000-6,000 quite easily. Can I start using a 50-50 mix of PYB and PP or PU? I don't want to switch to full conventional since my car has use synthetic for around 80,000 miles.

If this is a dumb idea to save money yet get a good mix, I'll just go to PP or any full synthetic that isn't a HM oil.

Just because you have used a HM oil once or twice doesn't mean you are stuck with it.

Why did you use M1 HM instead of regular M1?

Instead of mixing 50/50, why not just stick with PP for 7500 miles? It is a good price for a great synthetic. I don't think you will save that much money doing 50/50. You will only be saving a few dollars for a couple of quarts each time. Might as well pay $4 ish more and have all synthetic.

Just my opinion.

Just going PP is the best option IMO.

Should be fine

You can blend any ratio of syn and conv. But buying in 5 qt jugs is cheaper than buying individual quart bottles. So in order to save money, buy a 5 qt jug of each (PYB and PP). That way to save money and have enough for two OCIs.

Your 50-50 idea is a good one. With any major oil brand, then that proportional mix will be fine for 6K OCIs.

+1...I agree that you should stick with a full-syn.

If $$ is tight....take advantage of the QSUD deal...and you can get a pretty good full-syn oil...almost for free... if you purchase it at WallyWorld.

Just my opinion.

This. Unless you're maxing out an OC, a mix of near anything would be fine.

Thanks, I will do just this. Off to Walnuts or one of the auto parts stores after checking prices. since I don't need filters, Walnuts would probably be the cheapest.

EDIT: I meant I will do the math and go 50-50 if I save enough. If not, I'll just use a good Syn if it goes on sale...probably will try to stick with PP if all syn.

 

[HK_Ace]

Oh, I used HM because I was under pressure. The Autozone lines were getting long and I hate lines. So I grabbed it and ran to0 the counter, thinking it would be fine for one OCI since my car is HM. Why was I in a hurry? I had to go snowshoeing and was running late...and I hate crowds while showshoeing. It's all about being away from people.

Give the M1 HM a full OCI, and then compare how much you like it against PP. I think if you keep an open mind, you'll end up liking M1 HM as well, if not better than PP.

+1.

Oh, definitely will give it a full OCI. It would be too wasteful to change it early. Plus the QS rebate has drawn my attention.
