Mobil Delvac 15W-40 in my '24 GR86

[Son_of_shots]

I have shifted to this oil bc of the higher I will lug the engine or even put a higher load on bearings when starting. It calls for 20wt. I changed that to 30 wt but after some thought went to the 40wt.

I originally was going to keep the vehicle 3 years but I love it so m uch I am going to keep it longer. I think I will 100% waste my mponey and to a UOA afer the oil is in 4000 miles. Just curious to see the composition of the oil.

Only 0w20 will work correctly in this engine. Anything else will cause premature engine damage, & you will not be paid on warranty claims.

Sorry grasshopper..you have much to learn.

@Son_of_shots Please explain exactly what engine damage will occur in this engine if 0W-20 is not used.

Well I changed my mind again. I will go with the Delo 600 ADF 10W-30. Next change.

Why are you lugging engine (and are you actually really "lugging" it)?

I don't mean to and its not really "lugging" but its manual and it just happens

Why not just hold gears longer and run at a slightly higher average RPM around town?

Trying to select an oil to circumvent this sounds silly to me when you can simply adjust your driving habits to alleviate the issue altogether. To me this is like asking for tires with tougher sidewalls because you say you can't stop hitting curbs when you park.

I think Delvac 15W40 is a great lube for the money - Noack just above 10 bcs of the @XOM EHC upgrade - but yeah - another 500 RPM’s before the shift and 10W30 seems to feel right …

So you’re saying that women drivers should have tires with tougher sidewalls?

I basically switched all vehicles to this sauce:

And occasionally this one:

But now seems there is a full synthetic version for not much more money. So I think I'll switch to that, for as long as it's available on Wal-Mart shelf.

I'm 100% sure that none of my vehicles will ever have an oil related issue, as I never go above 5000 miles, and in some vehicles as little as 3000 miles. Two wheeled vehicles get 1500 miles.
K.I.S.S.

P.S. I love Mobil1 Euro offerings, but with my intervals that's just a waste of money. If I ever need better cleaning than HDEO provides - an occasional bottle of Rislone should take care of things just fine.

Been lots of debating over those “airing down” to 15 psi - guess they don’t realize what that does to a tire carcass - can’t go by tread depth alone if allot of that has been going on
40k and they come off my Jeep …

Remember the higher the grade the more heat the oil generates due to increased friction.

And reduced ability to get heat away from the bearings and rings.

Subaru oil pumps push enough volume even at 2k there is zero need to go to a thick HDEO for tooling around town.

Sounds like you’re holding onto some misconceptions. Just because a given HDEO may be higher in detergents, detergents do NOT clean deposits in an engine. Only oils with alkylated napthalenes & certain esters do.

The cleaning I mean is not the cleaning that's likely visual to human eye. The cleaning that I was able to achieve is the type that quiets noisy lifters in neglected engines. At that Rislone is great, from budget options. HDEO alone should be strong enough to keep things clean and avoid leaving more deposits after itself.

Are you going to do a UOA?

Yes
