Where to now, Amsoil?

[thetricky]

Speaking of, I've been considering switching my 22 wrx that is stock power (for a bit) to amsoil 5w30 or 0w30. I believe they're API SP? Also, would it be a waste of money if I plan 3-4k miles OCI?

I'm looking for a relatively thick 30 oil (the Valvoline R&P I use is 3.24 HTHS/ 10.4 kv100) . How does the amsoil xw30 compare? I looked online but didn't find info

If you go sig series you can go much further than 3-4k, even in a turbo boxer, it’s really stout oil. Arhat being said it may still be worth it for the ring cleaning/keep clean properties.

I'd probably do 3-4k then a UOA to see if 5k is good. Just not sure if the price is worth doing 3-4k oci overall.

I'd bet 5k is a walk in the park for it. I know it isn't the same application, however, the Amsoil Metric motorcycle 10-40 in my ninja is incredibly stout. I try to kill the oil everyday, 13k rpm shifts, 6th gear pinned and just keeps holding on!

Which Amsoil 5W-30? There are multiple:
https://www.amsoil.com/c/motor-oil/2/?zo=515729
https://www.amsoil.com/p/amsoil-signature-series-5w-30-100-synthetic-motor-oil-asl/?zo=515729

Both of Amsoil 0W-30's are not API listed, but do exceed all the test requirements.
Euro 0W-30 is 3.5 HTHS, 12.3cSt, SS 0W-30 3.09 HTHS, 10.4 cSt.
https://www.amsoil.com/p/amsoil-0w-30-ms-100-synthetic-european-motor-oil-eot/?zo=515729

You could use any of the above with no problem - also later for a WRX a 0W or 5W - 40 would be something to look at.

The first link isn't working. I'd like to stick with API SP-RC for warranty purposes.

5w30 SS is what I was referring to. Thanks

Fixed it, sorry I tried to have all the 5W-30's in a single link, didn't work

Anyway choose the OE, XL or Semi-syn if you want API listed.

In fact, if you want to run the semi-syn for 3-4K and do a UOA, I can hook you up, no charge. But there are some strings like doing two UOAs and posting them here, committing to not running off! hahaha

I appreciate the offer but I'm trying to stick as close to the owners manual as possible for warranty purpose.

What does the owners manual say EXACTLY?

I thought I specifically said synthetic only. It says 0w20 but 5hicker may be used in warm weather. I'm in Georgia, so I use 5w30 now.

Full 5 qts of any of the oils I mentioned will not void the warranty. Now perhaps a XW-40 would, because not mentioned.

Is semi synthetic ok for the 2.4 turbo boxer? I've only ever used synthetic in any car I've had

Of course especially under 5K. I wouldn't use it for extended drains for sure.

 

[SubieRubyRoo]

Some measure at a higher viscosity at 100c (KV100) and some have a better HTHS. That said, I think reducing how much an oil shears/thins over an interval is also important.

The HPL No VII Euro has virgin measurements of 3.56 HT/HS and 11.19cSt@100C. Plus it’s proven to lose less than 1% viscosity from shear; something no other oil we’ve seen can match.

@Pablo would be your source for Amsoil specs on the appropriate oil for your Rex.

Please DO NOT use a Resource Conserving oil in any turbo vehicle you intend to keep past the warranty period. It’s got even thinner base oils and higher levels of VII. You’re past the “infant mortality” zone on your engine; failures due to oil will be near zero. Buy the oil that will protect everything except a couple tenths of mpg. Other than receipts, it’s unlikely they could ever tell the -RC oil from a non-RC oil.

I'm leaning towards amsoil ss 5w30. I really don't care about long drain intervals. I want to protect my engine and keep it clean. I do 3-4k oci and won't change from that tbh. I could see 5k if I do start on amsoil SS

Grab the M1 0W30 ESP for 28 bucks 5qt jug at WM and be done with it meets some of the toughest approvals on the planet.

I wasn’t referencing going long intervals. RC is purely for additional CAFE credits. The additional VIIs in RC oils are not guaranteed to be the shear-resistant type; in fact they likely do shear some for additional MPG benefits, at the expense of long-term cleanliness.

The Amsoil is a safe bet. But always, periodically analyze your oil at expected OCI length to make sure the oil has not been overwhelmed. While you don’t want to ignore “wear” metals on a UOA, you’ve checking the viscosity, TBN, fuel & coolant levels to ensure you’re less likely to cause any accumulations.

If you're going with Amsoil, def go with SS.

I'd probably do 3-4k then a UOA to see if 5k is good. Just not sure if the price is worth doing 3-4k oci overall.

It depends on your budget. If Amsoil SS every 3K miles will impact you financially, then I wouldn't bother. If the cost does nothing to your budget, then I say do it. For me having three TGDIs, I like spending a little extra money to have the ultimate protection even if my OCIs are at the Severe recommendation. Doing the UOA is a good idea. I did it and realized that the amount of fuel dilution pushed me to stick with the Severe OCI.

I want my cars to last and I don't want to risk me or my family members being stranded somewhere or getting into an accident if the engine fails. Paying for SS is worth it to me.

I could definitely afford it. And it'd still be cheaper than dealer oil changes.
