lee07 Posted April 12, 2012 Share Posted April 12, 2012 Since when did our car's "eat" oil? Should I feed it some food too! It must be really hungry. 8 years now and I never fed it any food. Sorry Car! Cars have a taste bud? Link to comment Share on other sites More sharing options...
Apex-XT Posted April 12, 2012 Share Posted April 12, 2012 Saw a recent article on oil related to my wife's Toyota Highlander Hybrid... Issue is that Hybrid owners aren't getting the mileage claimed by Toyota. Toyota has now gone to using 5w-20 oil instead of the 10w-30 stated in the owners manual in attempt to improve gas mileage. It appears to work slightly. In the same thread, someone questioned whether the 5w-20 provided enough lubrication. Another responded that in their Ford police cruisers, they've used 5w-20 for years and have put high mileage on their motors with no adverse effect. Further stated that Ford now recommends 5w-20 for all cars. So, I'll probably try out 5w-20 Amsoil/Rotella/other combo based on the feedback here and see if I can get an improvement in both mileage and oil burn. 300k miles, BNR 16g, CryoTune, 'Bullet-Proofed' IC, Motor rebuild @ 250k b/c of a cracked exhaust valve. Original 5 EAT. Oil changed religiously @ 3,000 mi. Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted April 12, 2012 Author Mega Users Share Posted April 12, 2012 I wouldn't put a 5w20 in a turbo subaru, but that's just me. Link to comment Share on other sites More sharing options...
bluesubie Posted April 12, 2012 Share Posted April 12, 2012 Anyone use this? Didn't know they made the Ultra in a 5W-40. Pennzoil Ultra Euro Synthetic 5W-40 Motor Oil I'm running their "Platinum" in my Suburban and have heard good things about the Platinum and Ultra. I run Total (previously Elf...German) 5W-40 in my Subie. Have you actually found it? I ran it once when I got a case of 6 for free from Pennzoil. It was a 6,000 mile interval but the uoa results were a bit skewed IMO since I used two quarts of make-up oil. The uoa is posted on nasioc and bitog (I can't view from work) and I had to use PU 5W-30 for the last quart of make-up oil because I couldn't find the 5W-40 (not even at the Ferrari dealer!). The consumption may have simply been from switching oils because that occasionally happens when switching brands because of the different chemistries. IIRC, it is on the thin side of a 5W-40 (like M1 0W-40) which is ideal if you basically want to run a robust 30 grade oil. -Dennis Link to comment Share on other sites More sharing options...
bluesubie Posted April 12, 2012 Share Posted April 12, 2012 I wouldn't put a 5w20 in a turbo subaru, but that's just me. +1!! Why is a turbo Subaru being compared to a Prius anyway? Although, a Resource Conserving 5W-30 likely shears to a 20 grade anyway which is why I don't run those either! -Dennis Link to comment Share on other sites More sharing options...
No DRFT Posted April 12, 2012 Share Posted April 12, 2012 I like the castol syntec 5w-30 (it's been renamed for some reason to edge i believe) but my oci is around 2500 miles. I have no control over drippie. Link to comment Share on other sites More sharing options...

famaya26 Posted July 15, 2012 Share Posted July 15, 2012 Rotella over here since my last oil change two weeks ago. No consumption yet. Link to comment Share on other sites More sharing options...
fishbone Posted July 26, 2012 Share Posted July 26, 2012 M1 5w30, GC 0w30, PP 5w30, PP10w30, PU 10w30 All burn off to some extent. Pennzoil burns the least. M1 the most. GC was about in the middle. Used it once, never again (not worth the $). Using PU 10w30 year round and the burn-off is less than a quart in 4K miles. Link to comment Share on other sites More sharing options...
korpsepatrol Posted August 1, 2012 Share Posted August 1, 2012 Penzoil Platinum for 25k miles (subaru oem blue oil filter) Penzoil Ultra for 12k miles(maybe half a quart of consumption every oci of 3k) (puraltor pure one oil filter from here on out) Penzoil Platinum for 8k cause i couldn't find ultra anymore in my area Now using Rotella T6 5w40 for the last 700 miles and I gotta say car seems to run smooth on it. Platinum seemed to be heavier than the Ultra even though both were 5w30 2008 6mt Legacy Gt Spec B DGM - Not so Stock/Work in progress 2006 5mt Legacy Gt OBP - Sold 2005 5eat Legacy Gt OBP - RIP R.I.P Coxx Link to comment Share on other sites More sharing options...
05 LegacyGT Posted August 1, 2012 Share Posted August 1, 2012 Why did you switch from the OEM filter to the pure one? Was there something you like better about it over the Subaru filter? Just wondering because I'm planning on switching from the pure one to the Subaru filter my next oil change. Link to comment Share on other sites More sharing options...
05 LegacyGT Posted August 1, 2012 Share Posted August 1, 2012 I've used Eneos 5w30 and PU 5w30 with no consumption at all. Link to comment Share on other sites More sharing options...
fishbone Posted August 1, 2012 Share Posted August 1, 2012 I use PureOne as well. Works better than OEM per oil analyses and is at a decent price. Link to comment Share on other sites More sharing options...
